Minority Report, Kinect-style

Here's another cool hack using the Kinect, albeit one beyond the reach of most of us.

Some students, staff, and professors at MIT have developed "hand detection" software using the Kinect's motion sensor.  Below is a demonstration of this software.  It recalls Tom Cruise's iconic scenes from the movie Minority Report.

Brick by brick, it seems like science fiction movies are coming true.  First The Matrix and now Minority Report.  What futuristic fantasy will the Kinect enable next?

I'm both scared and excited to find out.
