How can mixing F#, the Kinect for Windows SDK and LegoNXT not be cool? This might give you a few ideas to play with over the weekend...
I've been having some fun playing with the Kinect SDK and the Lego NXT kit. The protocol to talk to the Lego brick over Bluetooth is pretty straight forward. Below is a little F# module for most of the basic commands
Using this along with Kinect skeletal tracking makes for a quick, pretty cool little project with the boys!
