It was only a matter of time - here's a mixed bag of the latest Kinect hacks...enjoy!
"I used the Xbox Kinect sensor to extract the silhouette and project it back as a shadow to the prison corridor. There are 3 seconds delay between the shadow captured and projected, make it a relation between a person and his past."
"Using Mac OSX and OpenFrameworks. A single camera with a Z depth. Impressive results. Thanks to the openframeworks developer community."
"Made with Cinder and the Kinect sensor. Runs in realtime."
