If you're looking for an awesome, impractical way to make music with your computer (and who isn't?) please direct your attention to the following Kinect hack. Shinect, the brainchild of a YouTube user named Shinyless, uses motion detection to turn you into a MIDI controller! The current implementation gives the operator two virtual pads that can be activated by the old Jersey Shore fist pump -- and if that ain't enough, the sounds can be pitchshifted by raising / lowering the other arm. Pretty sweet, huh? This thing uses OpenNI, and while he's demonstrating it using FruityLoops it should work with any MIDI device. Things are pretty rough'n ready at the moment, although he promises big things in the future.
