Use a camera or sensors so that you can dance to actually make money. You assign a snare to your left elbow, trumpet to your knee etc. Then you dance like crazy to see if you can make some good sounds. Then you put it in latin mode, so that when you rumba it sounds like latin music (hips gets points).
You could then apply this to gym or dance classes so that you can literally HEAR when someone is not doing it right.
Probably xBox or Playstation game.
