Without an official software development kit for Kinect, people have been able to whip up hilarious, often times neat results. With the Kinect for Windows SDK out in the wild? I think we’re in for a real treat.
You can find out more about the SDK — which features are included, what the license entails, etc. — and also download it from this page. I could easily see this leading to more inventive uses of the device than Kinect Fun Labs ever will, not to completely discredit that initiative.
Experimenting with Kinect, in any form, is a very good thing.
