3-Dimensional Holographic Projector
I tend to believe this is all possible.
I remember going to an arcade and seeing this technology before...It was quite some time ago too, I'm talking in the early 90's.
You would go up to the arcade game and your character would be a, careful here, TWO DIMENSIONAL hologram.
You could walk 360 degrees around the game that was shaped much like a table and only ever see one side of your character.
It was still quite impressive though.
Actual location of the said video game: West Edmonton Mall Arcade in Edmonton, Alberta, Canada.
