The guy has been fascinated with holograms ever since he saw his first one in Star Wars. You know Princess Leia coming out of R2 D2. I think most of us were fascinated with her for another reason but anyway. This guy liked the idea of holograms so he started building his own and this is what he came up with. Many are saying it is the closest thing we have to holograms right now. I don't know I think they have done some pretty cool stuff with Ronnie James Dio myself check out the second video.
