On his website this month, Chris O'Shea revealed he has hacked Microsoft's Xbox Kinect accessory to allow users to engage in air guitar sessions. There is video proof of the working hack (embedded below), which was ported over to the peripheral from a project O'Shea performed back in 2007 with a stereo camera. The program was written in C++ in openFrameworks and openCV for image processing, with ofxKinect and libfreenect drivers used on the Mac making the hack work.
