A quick glance and it could just look like a plant in front of a window, but you are in fact looking up through the atrium towards canary wharf tower.
This is another lunchtime photo, and another taken at canary wharf! I managed to snap this quickly as I had been spotted by a security guard and I had a feeling he wanted to exercise his powers and stop me photographing...
Great picture! Congrats on hitting Day 100! I love hearing you mention Canary Wharf...my company has a large office there, and I was fortunate enough to travel there on business for a week. Are you familiar with the Thomson Reuters building?
