On the bus to work, on a cold morning, I was looking out the window crossing London Bridge and all you could see was a sea of bowed heads. It struck me that, isolated from the cold on the bus, it looked like a load of people looking for something on the street, as though there was something interesting on the pavement they were trying to find. I decided to therefore dedicate today's shot to stopping at some point and seeing what - if anything - was interesting under my feet.

Just as well I fixed my iPhone though, another day where I forgot a memory card and all I could use was my phone :)
