A hacker says he can control Microsoft's Kinect, the just-released motion-tracking game device for the Xbox 360, with a Windows PC. 

The feat, by a member of the Natural User Interface Group, comes just days after Adafruit Industries offered a $2,000 reward to the first person who published open-source drivers for the Kinect.  Microsoft can't be too thrilled, since they spent years working on making it secure - and if it happened so soon after a paltry reward it may mean an Xbox 360 isn't needed to use it at all.
