I _think_ that it was the Night's Dawn Trilogy* that had laser projectors that would spot where your eyes are and then project images into them so that you got your own private 3D screen.
Microsoft have made one of those. Ok, so it's not lasers, it's LEDs, but it uses what looks like an industrial Kinect hooked up to LEDs and lenses that spot where your eyes are, use head-tracking to work out what your view should be, and then project the correct view directly at your eyes. And it works with multiple people, so that you can each be watching different things.
I am _very_ impressed.
Looks like it's a few years out at the moment - but when they get the speed and resolution up this will revolutionise computer games (and 3D CAD).
