Previously on Makezine I posted up a POV (Persistence of Vision) round up and this seems like the Logan's Run end game of LED arraying- the Revolver. This MIT Media Lab project uses the same technique as most POV projects, but revolves the flat plane of blinking lighting to potentially create 3D images. Check out the site for images, source and videos. Has anyone ever made a POV metronome?

Actually, some of the guys I camped with back at Burningman 2001 made a variation on this. Instead of making something that moved, they made a 5' column of leds that flashed the image and YOU had to shake your head back and forth to see the image. It was a lot of fun to watch people standing around shaking their heads. :)

The guy referenced by this post disses Actuality Systems, but they've got a high-res full-color version of this for sale now, and the dude that founded it made something much like this guy's LED thing ten years ago when he was an undergrad.
Heck, you could make your own high-res full color 3D display: just take the back off your laptop screen, strap the laptop on a high-speed turntable, put a strong light on the other side of the table, and spin... oh, and get yourself one heck of a video card...
(Let's see, at 20 3D frames per second (ie, 20 rotations per second) and with a screen running at 640x480, where you want the voxels of the outermost cylinder to be roughly cubic, that gives Pi*640 frames per 20th of a second...oh dear...)
