Hi Mona!
So how did it work? The little demo in the barn used a smoke filled glass container on which the laser *painted* the image. Basically just like a laser pointer works.
How it work in front of the Planet? Easy: They took a monochromatic laser, no smoke and pulled off a solid, full-color projection of Superman, including the sound. Common entertainment technology in the mid-nineties, right next to the replicator in the kitchen. $99.95 at the Costmart near you.
No, but seriously. Just take the laser holo-projector, have the computer render the images you want to project, and hit play. Just make sure the whole contraption has a perfectly still surface to stand on and adjust the beam's telemetry as needed.
I hope this helps, Michael
