Laser Art

What do you get when you mix artists, lasers, and computers? You get laser graph night at the 46! With a bright green laser, a computer, a web cam and a projector, it is possible for the computer to read the movement of a light source(laser, cell phone light) and convert it into a line. Graffitti Research Lab has been experimenting with light graffiti for a while and released some free downloadable software so any one with the right set up can get up.
