What if you had a camera that for the movie filmed at all focal forms (i think they have one) and then wore glasses that payed attention to eye movements so that the screen would alter focus such as to what your eyes were looking at… be neat in games too i bet…
I think they have something similar to that already out. pretty damn expensive little toys. Holographic games and TV I think, I remember seeing at least the game version a few years back at one of those rather large chain computer stores. It was being demonstrated. Frigging awsome, but so was the price tag.
