A couple years years ago, I saw this video. I was pretty excited when I watched it, because I could see the conception of three of my favorite sci-fi things...the holodeck, light bridges, and hard light Rimmer.
And then, I saw this. My thought was, "Uh, oh...here comes a revolution!"
Then, over the past year or so, Microsoft started delivering more and more technology and applications that are driving towards a full-fledged, in-your-own-home holodeck. (I tried to find the video of the reactive glass that would eliminate a need for glasses, but it seems to have disappeared or I'm just remembering it's project name incorrectly.)
