This system is incredibly expensive.  There is a 2 foot transparent plastic
dome that houses a large mirror mounted on a spindle that runs up the
vertical axis of the dome.  The spindle rotates the mirror at high speed
while lasers "paint" the image on the surface of the mirror.  You can barely
see the mirror, according to those who have seen this system.  The image is
contained within the mechanism of the dome (ie none of the image is projected
out into space).

The famous holographic chess-war from Star Wars could be accurately produced
with a system like this.  But there would be a dome around the chess-board,
unlike the movie.
