What would be more practical though is the use of goggles that totally shut out everything. The only thing visible would be what your viewing. When virtual reality matures I think we'll be using goggles for games instead of monitors. I experienced a very primitive version of this at Epcot center many years ago. You turned your head and could see what was to the right or left of you just like you'd imagine. The game was pretty lame though, you walked around picking up balls (with your virtual hand via a glove) and throwing them at opponents, the graphics were pretty basic. I don't think these will replace monitors all together though because monitors would still be more practical for work applications and viewing a movie in all directions seems ridiculous. But couldn't you imagine being in the midst of a battle scene from Saving Private Ryan with bombs exploding all around you? It would both terrifying and thrilling to say the least.
