Ja! A gentleman known to the Internet as Nitrogen has put together a type of Kinect do-it-yourself project that’s certainly worth a moment of your time. The “hack” uses the libfreenect library to turn the Kinect into a home automation sensor. So, you walk into your room, the Kinect camera sees you enter, then libfreenect turns on your lights. Leave the room, out go the lights.
Thankfully, there’s a video that shows the hack in action. I actually think it’s quite neat, not to mention useful, and we all know quick I am to call something silly.
