Polystyrene Polymorphism From Scratch, London

I was so tired today so getting up for work and forcing myself on to my usual train just felt really draining. Even at lunchtime I had to push myself to get out of my studio. I'm so glad I did otherwise I wouldn't have got today's shot. I decided to go for a meander, turned into this street and then saw this boy interacting with this surreal display. I just waited a minute or so to see if he would do anything and then suddenly he bent sideways to scratch his leg and there was my image!
