With MikuMikuDance and Kinect you are Hatsune Miku. This 3D music video maker for PC has been adapted to support OpenNI for real-time skeleton tracking. Once set up with Kinect plugged into a computer you can make a Hatsune Miku model follow your moves.
Right now, there are some bugs, like tracking a users lower body, but it’s still a neat little program. Perhaps, one Sega should check out, just in case they want to make a beat touching Hatsune Miku game for Xbox 360.
