I found the coolest thing today! AM Radio has an interactive exhibit at IDIA Laboratories. Go there and click on the spray paint can near the trains and you can tag the cars! It is really fast and easy. Once you design your tag, it is uploaded to a Flickr group and then uploaded to the train cars. As each new piece of art is uploaded by someone, the art moves to the next car over.
i'm too lazy to check the number i was on..
