MMaximus has uploaded a video of himself playing Stepmania with Kinect.
This is how he describes his hack
“Actually, I love PIU and I decided to play it with Kinect. Since I saw Keyboard Anywhere hack, I knew it was possible. But I have no idea how to make it. What I’d like to do is place the buttons on the ground and just step on them. I know it’s possible.
So I thought “DDR is easier to make, let’s try” and the result you watch now. ”
