Recording of the live presentation at Blender conference 2012(just days a go)
Basically these guys(Julius Tuomisto and the team at NI MATE)developed an addon(get it here) for Blender that allows you to use input from the Kinect sensor! Not only can you use the input to collect mocap data, but ther really freaky thing is you can also use it as a controller to interact with the Blender Game Engine! Heres one excellent example they have used it in – Interactive Storybooks
heres one of their tutorials for doing mocap
The Blender Game engine is quite fun to use.. i havn't posted much about it.. but have been using it.
