Going to correct those making comments on no-glass's 3D. There will never be true "no glass's" 3D on a flat 2D surface, physics doesn't let you do that. The best you can get is to design the screen in such a way that setting your eyeballs at a specific spot will enable each eye to receive a slightly different picture then the other one. Move outside that spot and the entire effect vanishes as your eyes are no longer lined up properly. The whole purpose of "3D glass's" is to channel / filter the image each eye receives to ensure the effect from a wide variety of viewing angles and distances. Upcoming holographs are a separate thing entirely and will probably be the eventual future of 3D. I've personally used several "no Glass's" screens and they require you to have your head in a specific spot to work and while this is neat its not nearly flexible enough for day to day use.
