Chinatown Roof Graffiti

I cannot remember when it was but I caught a taxi over the Manhattan Bridge and noticed all this graffiti on the roofs of the buildings on the Manhattan side. It was only just a glimpse as I was speeding past in a cab but I had always wanted to head back to shoot a couple of pic's. I managed to get back there the other week and was really quite amazed by the extent of the graffiti. Sadly it was quite late in the day and the sun was behind the buildings so the pic's were pretty crap but you still get the drift.
