The Kinect 3D Camera is a real gamechanger. Especially for interactive installations the possibilities are endless. Some of the experiments I’ve successfully done include:

-getting skeleton data
-controlling virtual characters in Unity3D with realtime motion capture
-mapping a space into zones to make the space interactive
-capturing objects and rooms into a 3D model
-motion capture
