Judge for yourself. Someone claims to have written a driver for the Kinect's motor, and he's extracted a Kinect's-eye view of what players look like to the device (above).
A while back we had a series of monochromatic shots animated together, showing you how the Kinect recognizes players. This gives you a better view of it. Below, you can see NUI Group user AlexP controlling the Kinect's motor.
Forum commenters at Adafruit, offering the $2,000 bounty for hacking the device, speculate that controlling the camera's motor is perhaps the easiest feat in hacking the Kinect. The skeletal imaging is pretty cool, but reading the terms of Adafruit's bounty, it sounds like just seeing what the device sees doesn't win the challenge. But it's probably a step along the way.
