The latest in Graffiti-tech: How to write with your eyes.
"Behold the latest ocular assault weapon from the Graffiti Research Lab, openFrameworks, The Fat Lab and The Ebeling Group: The EyeWriter. It is a low-cost eye-tracking apparatus + custom software that allows graffiti writers and artists with paralysis resulting from Amyotrophic lateral sclerosis (Lou Gehrig's Disease) to draw using only their eyes."
Amazingly, you can make this kind of technology for only $50 dollars using a hacked PS3 Eye and a cheap pair of sunglasses.
