I just found this really cool site where you can be a bird and fly. Here's a description of the game:
"Fly like a bird over the cityscape. Find the hidden bag of chips and then you can poo on the traffic wardens below to get a good score. When you run out of poo, another bag of chips will appear somewhere new."
Enjoy... Here is the link:

I found the chips, but I couldn't make my birdie poop on anyone.
