The Kinect-A-Sketch: A Homebrew Robotic Sketcher

This video from Waterloo Labs shows a bunch of young, excited interns building what amounts to a computer-controlled Etch-A-Sketch. The project uses an Xbox Kinect sensor to find the nearest point in space and then transmits that motion to an Arduino board which in turn controls stepper motors to turn the Etch-A-Sketch knobs. Sure you could just turn the knobs yourself, but where would the fun be in that?
