This Mario 64 mod uses an Xbox Kinect to control Mario using real-life jumps and spins
Someone is using the Xbox Kinect motion sensors to make Mario jump and spin using real-life movements.
Using a modded version of Mario 64 on PC, the player is able to move around with the Xbox Kinect one-handed controller, but more importantly they can jump, spin, and crouch and have Mario do the same. At one point in the brief explanation video above, the modder mentions that you need to time your IRL jumps precisely to achieve Mario's triple jump move. I especially enjoyed watching the player spin around on the trampoline while Mario swings and launches Bowser to his demise.
The modder says they used a software called FAAST to make the Mario 64 mod work with Xbox Kinect. You'll see the UI for body-tracking in the video above, but I can't attest to how intuitive the software is for newcomers to modding. Besides, surely it's only a matter of time before Nintendo's ever-watchful ban hammer comes down on the Mario 64 PC mod.
