Well coding for fun has definitely been doing some very cool stuff. I have just checked it out and they have done a ton of stuff for Kinect. It is crazy.
The video is very long but interesting, so check out the Kinect overview to get a start with the Kinect. Good for getting an overview for a beginner.
A nifty little application that was not in the Kinect posts was this little webcam mounted with servos that is controlled via skype. Isn’t that cool. So you can control it remotely so you can get a better look at your friends face. or look around the room remotely without your friend moving the cam! The post is here and they have a video showing the demo. With code as well. So it isn’t completely boring. And I am listening to that video while I am typing all of this until I here something interesting. So naughty me. But I was just interested in the 3D earth sample. But if I try to fast forward then I always miss something. SO I just wait here and listen!
