Holy shit-- we knew the Eyebeam kids were doing some insane graffiti research, but this video is just nuts. Apparently they've found a way to make "LED throwies", little balls of LEDs that can be thrown and stuck to walls. In the video, you see them making the devices, and then throwing a hundred or more at the walls of the art gallery on the corner of 23rd and 10th Avenue. Nutty stuff-- more info as it becomes available.
