     As I recall, that is not a synthetic image.  According to the article in
the Geographic, they set up the standard holographic photograph stuff
(reference laser, image laser, I'm sort of fuzzy on this stuff) and an
elaborate trip mechanism to fire the camera (or whatever) as a ball bearing
was fired through a real crystal globe.  They had some neat pictures of the
whole setup.
