These were mainly shot over a couple of days in London. The weather was very overcast so I did struggle with some of the light. The cardboard structure came from an exercise we did at a conference and formed part of a City of Thought. Although the curves emerged slowly at first as with the other exercises once you start to spot them it seems that others quickly follow. It did find that that curves are a less common shape, possibly because of the locations I was in, and those that do exist, like the diagonals,  were generally man-made. Something I will look out for in future exercises.
