But does it actually make stuff look like you can reach out and touch it like the 3D movies at theme parks? I don't see how it would. This just seems like parallax.

You can do this with a Kinect for head tracking and people do that with homemade pinball machines using a TV as the table, and a Kinect to track your head, so it looks like the table is 3D down into the TV.

But I don't think it creates the full 3D effect with things looking like they are coming way out of the screen and like a tangible thing you can reach out and touch.
