you haven't seen proof of it because it would need to be video'd with a 3d capable camera, (not in any cell phone that i know of)  then the software sending the file would need to support 3D, and on your end you would need to view on a 3D capable device. Otherwise you get all of the criticisms that we see of it not looking so very different or special.
