Yeah, the idea has been around for a while. I remember watching TRON and the evil human had a big desk desk kinda like that. There's nightclubs in Las Vegas that use some pretty nice effects with tables that seem to react to items placed on it, images display in shadows, photos scrolling/rotating as they travel down the bar.... I think MIT was doing something with this a while ago. Anyway, it's all neat and I'm happy someone is trying to market it instead of keeping it as an R&D concept.
