No Projection Surface Left Behind
Here is another great video from TK labs featuring the Lightbeam "nomadic" pico projector. It's actually Microsoft Kinect paired with an AAXA L1 Pico Projector with the intent of creating a projector that can track and reorient the image it projects so that any surface can become suitable for display. Potentially anywhere will become fair game for projection. Make sure you don't miss the trick with the coffee mug at the end of the video.
