Here's a little Microsoft-aping-Microsoft hack: As it turns out, the Kinect's sensors allow it to turn any flat surface into, well, a Surface. Microsoft's Surface is a multitouch display that, despite being undeniably cool, has, due to impracticality, languished as a gimmicky tool in CNN studios and Las Vegas casinos. This video, from Patten Studio, shows how to use the open-source drivers to use the Kinect as a sort of impromptu Surface.
You project a video at any surface, and then point the Kinect at that projection. This allows you to not only move digital images around with a swipe, but also to place real-world objects on the surface and also be recognized.
