Is that a canary I see?

Doing some work in t' city this week. Amazing building I am in - boy this company has some money!!

I could see not only Canary Wharf, but also the Dome - you may just see through the gap. On the high res version, I could see a helicopter parked on the roof of the 'fat-ish' building just left of the middle of shot in the distance, ready to take off! I hadn't seen it with the naked eye. Fascinating city!
