Making waves and moving sediment

Dr Hannah Williams has been a Post-Doctoral Researcher in Physical Geography at the University of Hull since April 2017. Hannah is part of the Hydralab+ project, a large European project that brings together researchers to improve experimental hydraulic research to better address climate change adaptation issues. Here she talks about a recent set of experiments carried out at the Total Environment Simulator.

Mixed Sediment Beaches are commonly found at high latitudes around the world, including amongst other locations, along the coastline of the United Kingdom. These types of beaches can consist of a mixture of both sands and gravels, and behave differently under hydrodynamic forcing, such as waves, to those made up of a single sediment size. Although some research, mainly in the 1970s-1980s, has been carried out to gain an understanding of the morphological behaviour of these types of beaches, little is still known about the variations in the morphology of these beaches due to mixed sediment, and how they respond to the hydrodynamic conditions.  The aim of this study was to try and gain some insights into beach response using a physical model.

At the University of Hull, we are lucky that we have a large experimental flume available for research called the Total Environment Simulator (TES). The TES has a working area of 11m by 6m, and is equipped with pumps to allow recirculating flow and sediment, a multi-paddle wave generator for the generation of both regular and irregular waves up to ~0.3m in height (depending on water depth), and finally is equipped with a rainfall generator sprinkler system on the roof. During my time at the University of Hull, I have been involved in experiments using all of these systems, demonstrating just how versatile the flume is. The photo below shows the TES when it first opened in 2000. As a well-used facility, it doesn’t look quite so clean anymore!  

For these particular experiments we were only interested in the beach response under wave loading, so only the wave generator system was required. We constructed a large beach across the opposite end of flume, with a height of 0.8m at the rear, and extending 5m towards the wave paddles. This gave the beach an initial gradient of 1:7.5.To obtain a mixed beach, we chose two different sediment sizes with a large difference in diameter. The fine sediment had a D₅₀=215μm (often known as play sand as it is commonly used in children’s sand pits), whilst the coarser sediment had a D₅₀=1.6mm. To construct this beach, this required over 5 tonnes of each type of sediment (and this including bulking out some of the area deep underneath the beach with breeze blocks), which all had to be lifted into the flume and distributed by hand. The photo below shows the initial smooth beach conditions. 

In terms of measurements, there were two main parameters we were interested in, firstly the incoming wave conditions. To measure these, we had 8 acoustic wave gauges distributed throughout the flume (see below). These recorded information about the wave heights and periods, from which we can gain an understanding of the transformation of the waves as they approach the beach. 

The second parameter we were interested in was the beach morphology. To measure this, we deployed a Terrestrial Laser Scanner. This was mounted from the ceiling above the beach. After each experimental run, the water was drained from the flume, and the scanner carried out a full 360 degree scan of the beach surface.The image below shows an example of a TLS scan, in which you can clearly identify the top of the swash zone, as well as a berm which has formed part way down the beach, and ripples in the lower section. 

For the actual experiments carried out here, we attempted to replicate some of the influence of the tidal cycle on the response of the beach. The experiments were run at three different water depths, namely 0.3m, 0.4m and 0.5m. In three of the experiments, we hit the beach with an initial storm (H=0.18m, T=2.2s, where H is wave height and T is wave period), at different points in the tidal cycle. One at high tide, then one at mid-tide on the flood tide, and one at mid-tide on the ebb tide. The purpose of this was to try and investigate the effect that timing of the storm with relation to the tidal cycle has on the beach response. After each storm a number of recovery events (H=0.10m, T=1.5s) were carried out, at each depth to complete a tidal cycle. The video below shows some of the experiments in action.

Using the laser scans, we can also examine the differences between scans, giving us an idea of the evolution of the beach throughout the experiments. From these we can obtain information about the amount of erosion and accretion at different points of the beach, and examine if this is different depending on when the storm occurred. The image below shows an example of a Digital Elevation Model of Difference, from which a number of interesting observations can be made.  It should be noted that Red shows accretion of sediment, whilst blue shows erosion of sediment. 

The very top of the beach remains white, this shows that the beach level here remains constant throughout the experiments, due to the wave run-up not reaching this point. Just below this section is a large area of erosion, this is the swash zone, where waves are breaking. This is a very energetic area which results in a large amount of sediment transport, mainly transported further down the beach to the zone showing large accretion. This is known as a berm and often forms as the wave deposits sediment. Below this area, it can be seen that ripples form. This is prior to the wave breaking where sediment movement occurs in an elliptical motion, forming small ripples on the surface. These are all features that are not unique to mixed sediment beaches, however, one feature that is, are the beach cusps. These can be identified in the figure by the regular arc shapes present. There is limited information on the origin of beach cusps, but once they have been created they are a self-sustaining formation. This is because as a wave hits the area of the beach with the cusp, it splits at the point and the water is forced either side. As the wave then breaks, the coarser sediment falls out of suspension and is deposited on these points (known as horns), whilst the water flows into the arc (also known as an embayment) where it in turn erodes out the finer sediment.

These experiments have only just finished, so analysis of the results is still on-going, but hopefully we will have gained some useful insights into the behaviour of mixed sediment beaches which can be used to help devise beach management plans in the future.

Hull’s Protest Stickers

Dr Hannah Awcock has been a Lecturer in Human Geography at the University of Hill since January 2019. Hannah is interested in the cultural and historical geographies of resistance. Here she uses protest stickers to investigate Hull’s radical culture.

Stickers of all kinds are a common sight on the streets of towns and cities across the world. Stuck to lampposts, bins, utility boxes and other street furniture, most people probably don’t give them a second glance. Stickers on the street are temporary; some are gone in days, removed by people who didn’t like them or who picked them off when they got bored waiting for a bus. Others take months or even years to disappear, gradually erased by the weather or covered up by more stickers. Stickers come in a huge range of shapes, sizes, and designs: some are handmade whilst others are printed; some are only text, others use a combination of text and images; some are black-and-white, but most use colour. They are used for a range of purposes, including advertising and street art. Sometimes their purpose isn’t clear. I am interested in stickers that make a political statement; I call them protest stickers. Activists and campaigners use protest stickers as a way of claiming space and publicising their message. They can tell us a lot about how activists and protesters engage with public space.

Protest stickers like the one above are small stickers that covey a political message. They can be found in public spaces all over the world. Protest stickers can reveal a lot about the city they are in; they can tell you a lot about the local radical culture. Whenever I go somewhere new for the first time, I photograph the protest stickers I find. When I moved to Hull in December 2018, I was curious to get to know the city and see which protest stickers I would find. What I discovered is a wide range of protest stickers on a range of topics, as the selection featured below demonstrates.

 Anti-fascism is one of the most common topics of protest stickers—there is a strong tradition of ‘stickering’ amongst anti-fascist groups. There is also a strong association between anti-fascism and music, as this sticker suggests.

Whilst a lot of protest stickers relate to specific issues, some are quite general. This sticker is emphasising the importance of solidarity, one of the core concepts of activism of all kinds. Solidarity is the practice of offering practical, financial, and moral support to other activist groups and campaigns. The white ‘A’ in a circle is a symbol of anarchism.

Since the EU Referendum in June 2016, Brexit has been a popular subject of protest stickers, produced by both Leavers and Remainers. This sticker is produced by the EU Flag Mafia, which sells a wide range of anti-Brexit merchandise (you can by 100 stickers for £6 if you are interested, and they have several different designs).

This is one of the most unusual sticker topics I have ever found, and I have never found this sticker anywhere else but Hull. Biafra was a secessionist state in eastern Nigeria between May 1967 and January 1970. Biafra’s attempt to become an independent state sparked the Nigerian Civil War. The Nigerian military government effectively starved the people of Biafra into submission, and they surrendered. Some groups still continue to campaign for Biafran independence, and I would love to know what the connection is between these campaigns and Hull!

This is an example of a handmade sticker. It is playing on the double meaning of ‘colour,’ referring to both race and the more literal interpretation, as in red, blue, yellow, etc.

 

This sticker was produced by the Anti-fascist Network, but it is also promoting an anti-racist message. Three slanted arrows in a circle is a common symbol used by anti-fascist groups. It shows how protest stickers can be territorial, by claiming the surrounding area as an anti-fascist space.

This sticker demonstrates what can happen when stickers are not removed quickly. It has been partially peeled off, and large parts of the rest have faded away. I have seen this sticker before, so I know what it says. It reads “Fight War not Wars,” which is derived from the popular 1960s anti-war slogan “Make Love not War.”

This is another sticker that I have never seen anywhere else but in Hull. Protest stickers promoting vegetarianism and veganism are relatively common however. This sticker is encouraging the viewer to watch Earthlings, a 2005 documentary about how humanity uses animals in a variety of ways. Its design is simple and there is quite a lot of text. On way of analysing stickers is to think about how effective their design is. For example, which of the stickers in this post do you think is most likely to make you stop and read it if you saw it in the street? Why is this?

Most protest stickers are left-wing and/or progressive. Sometimes, however, I come across a particularly unpleasant sticker like this one. It is accusing all refugees of being prone to violence against women. In recent years, women’s rights have increasingly been used as an excuse for anti-immigrant sentiment, which could be related to the rising number of women in right-wing groups. The sticker was produced by Combat 18, a violent neo-Nazi terrorist group formed in the UK in 1992.

This isn’t strictly speaking a protest sticker, but I wanted to end on a positive note! Jean Bishop is a local hero in Hull, having raised almost £120,000 for Age UK over the last two decades armed only with a collection tin and a bee costume. She has been an inspiration to the city for some time, and in 2017 was awarded and British Empire Medal for her efforts.

In this post, I have attempted to show the wide variety of protest stickers that can be found on the streets of Hull. Perhaps next time you are out and about in the city, you will start to notice them too!

If you would like to see more of the protest stickers I have found on my travels, you can view them on my blog: https://turbulentlondon.com/category/protest-stickers/

WOW Week of Women in GEES: Lois Latham (1910-1990), regional geographer

by Briony McDonagh (with help from Helen Manning)

Today’s ‘WOW GEES woman’ is Lois Latham, a regional geographer who spent more than 30 years in the Department of Geography here at Hull. She was the first woman to be appointed to a permanent academic post in the department in 1946 and throughout much of her tenure, the only female academic working in the department.

(l-r: Jay Appleton, Alan Harris, Harry Wilkinson, Lois Latham and George de Boer) 

Latham was born more than a century ago, in Wakefield (West Yorkshire) in 1910, later studying geography at the University of Sheffield and graduating in or around 1932. She served as editor of the Scottish Geographical Magazine between 1936 and 1940 – the third woman in succession to hold the post – and during the Second World War, she contributed to the Admiralty Intelligence Handbooks.

In 1946, she moved to Yorkshire, appointed as a lecturer in Geography in what was then Hull University College. This was a time when the city was still hard hit by its aerial bombardment during the War. As a then colleague of Latham’s in the Department of Economics mentioned to me recently, Hull in the late 1940s and early 1950s was badly ravaged by war with thousands of bombed-out houses and many of the academics at the University working out of army huts!

During her more than 30 years at Hull, Latham was active in the teaching programme and in a range of other roles both within and beyond the University. She was President of the Hull branch of the Geographical Association from 1954 until around 1960 when she handed over the presidency to her colleague in the department George de Boer. She travelled widely and in 1959 to 1960 she spent a year at the University of Zagreb in Yugoslavia and later organised a return visit to Hull by Tomislav Šegota of the Yugoslav Encyclopaedia, an international connection linked closely to her own research interests in the regional geography of the USSR. She also headed the department’s contribution to the second phase of the Land Utilisation Survey of Britain, the behemoth of a mapping project first initiated by Dudley Stamp in the early 1930s. She was by all accounts also an excellent teacher, and the department continued until very recently to award a student prize in her name (funded thanks to a generous bequest in her will).

By the time she retired in 1977, Lois Latham had spent more than three decades as an educator and researcher in the Department of Geography. She had seen the University gain its Royal Charter (and the right to grant degrees in its own name), been part of the move whereby the department relocated back into the space in Cohen it now occupies and witnessed a huge explosion in staff and undergraduate numbers. During all this time she was the only woman to hold a full-time academic position in the department. In fact, it was not until the appointment of Sarah Metcalfe and Judith Rees in the late 1980s that the department ever had more than one woman in full-time permanent posts on the payroll! Today we’re approaching double figures – an achievement indeed in the quarter of a century since 1988.

But despite both her long-standing service and her role as Hull’s first female geographer, Lois Latham remains a relatively obscure figure. She was not, for example, someone I had heard of when I started my own job at the University, though I knew of other Hull geographers of the period including Herbert King (whose papers at the Hull History Centre I’ve previously consulted) and George Kimble (whose Geography in the Middle Ages I’d recommend to anyone). As Avril Maddrell comments in her recent book, Latham has been ‘expunged from the textual account of the department’s history’ (Complex Locations, p. 235). It’s hard to know whether this was directly as a result of her gender, but as one-time colleague Derek Spooner notes in his contribution to the department’s recent history, Latham was a ‘somewhat marginalised and possibly undervalued figure in the Department’ (Eighty Years of Geography at Hull, p. 14). She did not, for example, publish as much as many of her (male) colleagues and as we all know in academia, it’s publish or perish when it comes to one’s scholarly reputation. Personally I’m sorry she published so little – I’d have liked to have read the work of the Hull’s first female geographer. I’d also like to know which her office was in the Cohen Building. I’m definitely hoping it was mine!

International Women's Day (8 March) is a global day celebrating the economic, political and social achievements of women past, present and future. International Women's Day celebrates women's success, and reminds of inequities still to be redressed. The origins of IWD can be traced to the struggle for women to gain the vote in European countries about a century ago. The first International Women's Day event was run in 1911.

This City Belongs to Everyone

by Chris Skinner

Recently, I was tasked with designing five workshops for our Foundation Science programme to introduce Geography specific material to those students planning on studying it in the future. For one of these workshops I plan on looking at our city, Hull, and its surrounding area, asking how, as Geographers and researchers, we can get involved in understanding and influencing these. I want to demonstrate to my students that whatever your research area you can be invested in your local area.

I began by hijacking a Departmental staff email discussion to ask "what do you consider to be the most pressing geographical issue facing Hull?", and I found the responses interesting, highlighting how different research specialisms cause people to think of our local area in different ways. So interesting, I wanted to share some of the responses here with you.

Myself,  I would say flooding and the increased pressure caused by rising sea levels. This was shown clearly by the storm surge of December 5th 2013 - the tidal barrier at the mouth of the River Hull had just 40 cm left to spare and the minimum sea level rise predicted by the IPCC to 2100 is 40 cm. Obviously, the city will need to invest in better defences or other solutions. I wrote about this in a previous post.

In mainly short replies, several of the Physical Geographers here agreed in their responses -

"Flooding!" - Professor Lynne Frostick

"Climate/Environmental change, sensu lato." - Dr Jane Bunting

Professor Jack Hardisty, however, saw an opportunity to establish the city as the heart of the "Energy Estuary" as the most important issue. Many agencies are working very hard and with great success to create a hub of sustainable energy in the Humber, both in the construction of infrastructure (like the development of the Siemens off-shore turbine factory in Hull), and the generation of power, such as tidal generators.

Professor Jeff Blackford suggested "Economic inequality and lack of social mobility" to be the big issue, and he was supported by many of the Human Geography researchers.

“A combination of its structural economic legacy, urban austerity, and environmental situation” - Professor Andy Jonas

“Flooding and relatedly, the feeling that the place was abandoned and left to rot in the aftermath of the 2007 floods.” - Dr Briony McDonagh

I like this quote from Briony as it highlights how the issue identified by the Physical Geographers, the flooding, is intrinsically linked to those emerging from the Human Geographers. The flooding in 2007 needs to be understood in the physical sense to find out what caused it and how it can be avoided in the future, but also the impacts on people and their perception of the city and its place in the country needs to be understood. I find Hull has a sense of abandonment by the rest of the country that was either started or was reinforced by the bombing during the Blitz (and subsequent lack of reporting) - this same sense emerged post-2007 that the city was ignored in favour of other areas after the flood. Indeed, the major flooding on the 5th December 2013 slipped under the nation's radar somewhat too.

The National Film Theatre on Beverley Road was listed in 2007. It was bombed and burnt out in 1941 and was never repaired - it is one of the last remaining visible bombsites from the Blitz.

“The challenge of overcoming Hull’s negative (and inaccurate) imaginative geographies – on the receiving end of too many Hull or Hell jokes…” - Dr Suzanne Beech

However, one issue raised by Professor David Atkinson provoked a discussion. Here's his full response -

“The effects of the city of culture award before, during and after 2017

Hull as an under-bounded city (and current wrangles to fix this)

The elusive nature of place and ‘Hullness’”

A different resonance - Whereas the rest of the country had iconic red phone boxes, Hull's were white (although the tourist office still sold red phone box souvenirs)

(Image by RM21, from en.wikepedia under Creative Commons Licence)

I want to pick up the issue of Hull as an under-bounded city. What does this means? It is down to the way the city boundaries are drawn that exclude some of the sub-urban areas around the city, like Cottingham and Willerby. These areas are more affluent than much of the city and are not included when drawing statistics for the city, or contributing towards Council Tax to run the city's services (which many of the residents in those areas will use). This is a relatively uncommon situation and negatively skews many of the statistical indices for the city and reinforcing its negative reputation in the country. There are plans to rectify this, but as you can imagine it is not popular in those areas that may go from being within the East Riding of Yorkshire region to being with the City of Hull.

Professor David Gibbs also felt this was the major issue and highlighted some of the controversy, suggesting that this would be an interesting topic to look at as part of a workshop.

“I agree with [Professor Atkinson], the under-bounded nature of Hull and the debates between Hull and the [East Riding of Yorkshire] would be good and lots of on-line debates to tap into on press websites – see the Hull  [Daily Mail] website for a good deal of lively debate in the comments section!"

This issue was also picked up by Dr Kevin Milburn. Here is his full response -

“For a long time it seems the city’s location has been a handicap (or at least perceived as being such), to which I must also lob in the relatively poor transport connectivity of the city, especially to other cities and towns in the North. It feels like it would almost be quicker to get to, say, Grimsby or York, by unicycle than public transport. Now, however with renewed interest in the opportunities offered by the estuary, most obviously demonstrated by the recent Siemens investment announcement, perhaps Hull’s peripheral location might actually start to be something of a plus point. The city’s isolation/'end of the lineness’ – and supposed subsequent uniqueness – was interestingly used as a positive by the Hull 2017 bid team.

I also agree with the points raised re. Hull’s boundary and the impact this has on where Hull finds itself on national league tables re. schools, poverty, unemployment rates etc. I find it bizarre that somewhere like Romford can be considered, administratively at least, part of London (it doesn’t get more Essex!) and yet Cottingham, for example, is not part of the Hull metropolitan area.”

HS3 - Could a high speed rail link between Manchester-Leeds-Hull improve the city's connectivity?

(Image by mattbuck, from en.wikipedia under Creative Commons Licence)

David Atkinson raised further points that might contribute to the sense that Hull is dislocated from the rest of the country, something picked up above by Kevin - 

"- a lack of central government funds to assist with reconstruction after the war

- the sudden collapse of the fishing industry in the 1970s and 1980s, and the failure of national government to protect Hull's interests (as perceived by the locals)
  
- the decline of some other, traditional, heavy industries with limited central government assistance in the 1980s-2000s

- the rising sense that other cities and regions could sneer at Hull (reaching its height in the 2003 'Crap Town' accolade)"

I found this exercise really interesting and really insightful, and I look forward to seeing how the people involved above shape their future research in order to investigate the issues they've highlighted. I can't speak for the others, but I am sure it is true, but I love this city, my city, and whilst we're not blind to its issues and problems, we embrace its wonderful character and personality which, honestly, is unlike anywhere else in the world - that's partly why we won, and were so proud to win, the City of Culture status for 2017. Nothing sums it up better than the bid video - This City Belongs to Everyone.

I think my students are going to find the responses useful and I plan on having an enjoyable and lively discussion about them during the workshop.

Hull University Science Festival 2014

by Chris Skinner (@cloudskinner)

One of the great joys of academic life is getting the opportunity to communicate our research to the public - it is one of the key motivators of this blog after all. We spend much of our time in a bubble and become accustomed to our jargon and way of life which seems a bit alien to those outside the bubble, so it is also very healthy for us to step out once in a while and engage with those out there. The challenge is finding ways to communicate our research in ways that are informative and engaging.

This year, the Faculty of Science and Engineering at the University of Hull organised the Hull Science Festival. Running as part of National Science Week (which one attending school pupil pointed out to me was 9 days, and not actually a week), it saw students and staff from the university present their research to members of the public.

The Science Festival ran on a Friday and Saturday. Friday was an early start as the Hull Bondholders ("The Bondholder Scheme is an almost 200-strong powerful network of businesses, who work together to raise the profile of the Humber") held their regular breakfast meeting at the University as part of the Festival, which allowed us to explain the benefits of our research to business in the area. After the breakfast (after we had mopped up the leftover sausages - all the bacon had gone), the audience changed to school pupils and their teachers, as local schools were invited to attend.

Throughout the day the marquee containing the exhibitions was open for the pupils to mill around and chat to us, whilst the schools took it in turns to attend the presentations and demonstrations conducted elsewhere on campus. Unfortunately, I did not get the chance to see any of these. The pupils all seemed very excited and keen to know more about the displays on offer, and I also got the chance to chat to the teachers from my old school, Baysgarth, who had brought some pupils along.

The Saturday was open to the public to just come and go as they pleased and wander, and hopefully wonder, around. This was a busy day where I spent almost all of it talking to people about my research and the Humber. It coincided with an Open Day too, so prospective students got a further opportunity to see just what an active and exciting university we are.  All in all, it was a great couple of days and I hope it becomes a regular fixture in our calendar.

Unfortunately for me and my chances of looking around, both days were very busy and I spent much of it manning my stall, demonstrating the Dynamic Humber Project's work on understanding the 5th December storm surge, but I did get to see some of the neighbouring displays.

GEES were out in force for the Festival, as shown below - 

The view over the GEES displays

Dr Malcolm Lillie brought along skeletons and bones from his archaeology collection, including some pieces which were over 7,000 years old.

You say stomata... (photo by Dr Jane Bunting)

Dr Jane Bunting set up a microscope and gave people the opportunity to take peelings from a holly leaf. Observing these peelings under the microscope revealed the leaf's stomata (mouth-like pores that exchange gases and moisture between the the air and the plant) - this was to highlight the research into how leaf structure can change in response to weather and climate.

Prof Jack Hardisty brought along a prototype of a tidal generator which was used to demonstrate the potential of harnessing the abundance of tidal energy in the Humber to generate electricity.

Here, Dr David Milan demonstrates how changes to the land surface can influence run-off. Whilst the water on the hard surface drains the tank very quickly, the natural surface absorbs the water, holding it for longer and reduces the levels of flow - this can help reduce the impacts of flooding.

In addition to the displays above, we also had posters from other members of the Department, including showing off research in Human Geography by Prof David Gibbs and Dr Kirstie O'Neill, who showcased their research on green entrepreneurs  and the role they play in making building more sustainable. Dr Deborah Butler was often seen wielding an iPad ready to demonstrate the FoodCrowd app she blogged about last week.

We weren't the only ones at the Festival, not by a long shot, and below are some the highlights around the marquee - 

Beequiet and Beehave

Dr Darren Evans from the University's School of Biological Sciences brought along some bees in a commercial hive. Although largely confined to a netted cage, one plucky bee escaped and enjoyed a ride on the tidal generator. 

Biodiversity Jenga and Coffee! (photo by Darren Evans)

Dr Evans also brought along his giant Biodiversity Jenga set, which demonstrates how the successive removal of species from a system can lead to environmental collapse.

My favourite part of, my limited view of, the Festival was the 3D printer brought along by Computer Science. I love these things and have been following their development for years, but this was the first time I had seen one for real, and it was working! The potential for these things is enormous, and I'm not just saying that as a secret collector of toy soldiers. Computer Science also brought along a few robots and their Oculus Rift (virtual reality equipment, recently purchased by Facebook) set up which they aim to use to train people to install and maintain offshore windfarms from the shore.

Racing for Formula Student (photo by Hull University)

Also there were the Hull University Formula Student team. A group of Engineering students who have built a racing car and race it in competitions. Their demonstration included a sit in simulator where people could have a go themselves - there was also a leaderboard going for the fastest lap times.

Opposite me was a popular set of animal skeletons. I was told that these were donated to the University by the Natural History Museum in London when the University was founded in 1927. They are exquisite things, and included an ant eater, a horse, tortoise and a rhino skull.

Flying Magnets! (Photo by @HullUniScience)

Throughout the day I saw many people walking around with bags of goo, DNA sweets and all sorts of other goodies that were being given out. There were people extracting DNA from peas, and racing plankton (won by our very own Prof Dan Parsons) or even racing over a magnetic elevation track. Lots of fun was had by all and I'm looking forward to next year. If you attended the festival, why not leave a comment below about what you enjoyed most or what you would like to see in the future?

Whilst I was writing this post, as part of a ongoing series of elaborate April Fool's gags from Google (which has seen me collect all 150 Pokemon and desperately search for Mew), one of the photos used got "Auto-Awesomed". The result was too good not to share.
