It was bound to happen sooner than later. That’s right, Kinect has been hacked to work with Portal 2, though not perfectly yet. Powered by the FAAST toolkit, Brad Cooley “was able to get a Kinect sensor to track his skeletal body and map the infamous Portal gun to his arm.” Video after the break.
Like most Kinect hacks, the workaround solution is a little laggy and doesn’t run at full speed. Had Valve officially made it, I’m sure the geniuses over there could get the full game running properly.
