Yes, we have seen a lot of Kinect Hacks, and some of them are being used to create some interesting views of another person with its sensors and cameras.
It would appear that some guys at MIT Media Lab are figuring out a way to create something of a holographic effect like Star Wars, with a Princess Leia.
The Kinect-powered hologram transmitter uses a single-camera and can update transmissions at a speed of 15 frames per second. The video shows that the footage is good for 3D TV sets, which is good because none of us have holographic generators.
Well, this is definitely the way it is going to be in the future. Science-fiction communication of the future has taught us that.
