The animated "chess" game shown a few scenes later may be an even better
example. That could be arranged so the characters always have some part of
the "display" surface behind them, as in a real hologram.

Regarding differences in visual memory among individuals, the ABC News Web
page had an article yesterday (don't know if it's still on), with a very
interesting animated demo of a test of the speed of visual memory. One of
the items claimed in the article is that humans have a lot of trouble
retaining more than about four items at once in their short-term visual
memory.

Since viewing of a normal stereo photo consists in part of "scanning" a
scene and building up a mental model, that line of research might be of
interest to those who wish to design new stereo imaging systems.
