I have used this before... (Score 2, Interesting)

A few years ago I was able to use one of these systems (prototype). Truly a very awesome setup. At the time the unit was composed of a very light headset, which was capable of projecting a single color, red. The most interesting future feature presented was the ability for this laser to be shot across a room into your eye, eliminating the need for the headset. Since I saw the headset demo a few years back I am curious if they have perfected a means to do this yet.
