Kinect Hack allows for playing an invisible piano

It seems like we are getting a lot of neat Kinect Hacks like surfing the web, the Da Vinci physics, and then the Guitar Hero thing.

Now the Kinect can play another instrument, the piano. You can watch in the video how someone puts a keyboard in front of him.

The coolest application of this is to make a big keyboard like the one Tom Hanks and Robert Loggia in Big.
