You did laser holograph stuff? Sounds extremely cool, have yet to see actual holography as to this day however :/
Yeah, it was a pet project back then; was interesting though the Holograph we were trying to design completely failed when we had the day trip to URI. Was trying to do the same thing with the holograms in the original movie Logan's Run. Ended up missing a step and the shape never did come out properly.
It's going to be some years however before we see anything like the holograms we see in movies though. We're getting close, but it's not quite there.
