Don't you just love those 3D displays they have on sci-fi movies? I'm talking about the "data crystal" on Babylon 5, the hidden message that comes out of R2D2 on Star Wars and so on and so forth. Well, it looks like something of that sort is starting to emerge in the real world as well. My friend Sharona just pointed me to this great site that shows the beginnings of such a technology. Now if they could just get rid of the fortune-teller style crystal ball... ;-)
