"I'm just amazed that a 4-man splinter group can do something this amazing."
This is actually quite trivial. Fixed images (posters, pins) were done in 3D and moving pictures using this technology for years. They simply slap it on TV.
And actually, as 3D goes, this is horrible. You have "sweet spots", meaning you have to sit only in some places and do not move your head, otherwise, 3D will be spoiled.
What would be revolutionary, is if TV would find the location of the eyes for each viewer (I am sure Xbox360 can do it with Kinect) and send stereo images in the detection of each eye for each user. THEN it is good experience, because you would be able to move and still see the image.
