The Kinect is a hot device and many projects use it.
How about using Kinect with FEZ?
I think that it should be very exciting.
We had a discussion about Kinect a couple of weeks ago, don’t remember the thread though.
I was going to try it with ChipworkX dev board, but haven’t had a chance to do it yet.
We also spoke about the PlayStation move. Which I would find useful for robotics (positioning?) or quadrocopter stuff (sensoring?)
