Light-based grafitti

Nokia have published a video showing images, and behind the scenes, of video artists who have built a motion tracker using an N900 and a spare spray can: Lady Bna-nas, Madcheeze and Introcept are street artists from Australia. But for the 2009 Push N900 competition, they were known as the Light Hack Crew. They love graffiti but they also share a passion for technology. So they created an electronic spray can and hooked it up to a Nokia N900. The spray can creates an LED light source and the hacked N900 captures the beautiful time-lapse images. See for yourself.
