Dance Junkie

Dance Junkie is a full body Rhythm Smasher game that turns your webcam into a motion capture system. For players without a webcam, or who need additional computing power, a smartphone or laptop can be linked to the game through RealmConnect. Experience full body tracking without the expensive equipment while you move your body in a fully immersive fantasy world.

You have implants in your hands, feet and chest that allow you to pop "Tune Bubbles". Tune bubbles spawn in response to music, so you're going to need a bit of rhythm to be successful.
