As Kinect hacks go, this one's not going to bowl you over with its technical complexity, but the effect of what it does is quite dramatic. One of Microsoft's sensor-rich, camera-laden Xbox accessories has been repurposed to communicate with a Pufferfish spherical projection display -- via the magic of WPF and openni -- with its motion tracking algorithms serving to control the image on the giant ball. Naturally, the first thing the tweakers behind this mod thought up was a Tolkien-inspired eye that follows people around the room. Sadly, the single Kinect box isn't enough to provide 360-degree coverage, but it's probably just a matter of time until they splice an array of them together and creep us out completely. Video after the break.
Update: You asked for the eye of Sauron and now you've got it. Second video added after the break.
