Do you also find that the most simple seeming prompts cause you most challenge?
This one stumped me. I didn't seem to have any photos of two things and, for whatever reason, I couldn't see any during the week.
Until I spotted the O2 mobile phone shop and realised there was another way of seeing 'Two'.
Although this is in no way a pretty picture, I like how the letters seem to be floating in mid-air (they are transfers on the shop window) and the ghost books reflected from the coffee shop opposite.
