Well this is somewhat unexpected- Microsoft has announced that an SDK (software development kit) for it's popular Kinect motion controllerless camera array will be available for download later this year for the PC.
The intent of releasing a “starter kit” for application developers is to make it easier for academic research and enthusiast communities to create even richer experiences using Kinect technology.
The hacked stuff
without the SDK has been amazing- now that the system is all laid out for would-be developers? The sky's the limit is probably an understatement.
