Jean-Christophe Naour. This hack utilizes the Microsoft Kinect camera and creates digital graffiti from the motion of the user. The camera sensors detect movement and display colorful rays of light from the simplest motions such as a hand waive or finger twirl. This hack is still in early development but it's definitely an impressive display of technology. No word if virtual cops will be included in the next version though. Peep the video after the jump!
