There are lots of ways to fake three dimensions with two dimensional images: some crazy stuff is possible if you know what you're doing. But, this isn't real 3D. The only way to get real 3D out of a 2D medium like paint is to gradually build up a sculpture out of hundreds of layers, which is where these incredibly lifelike goldfish come from.

If we've had one thing hammered into our unwilling skulls over the last few years at CES, it's this: 2D sucks, and 3D is awesome. Nothing is better in 2D. Nothing. Not even pictures of your dog. Somehow (and it won't tell us how), Casio is able to take 2D snapshots, add depth, and then use a proprietary 3D printer to make sculptures out of them. The results, while striking, can be a bit strange, as with the (excessively?) pointy dalmatian in the picture above.

There's no shortage of 3D displays and TVs available for purchase these days. To many, the extra couple hundred — or sometimes thousand — bucks isn't worth the extra "D," but prices are slowly coming down from a year ago. Sony isn't giving up the 3D dream, though. The company is gambling hard on 3D tech, this year releasing the 3D TVs you'd expect, as well as some crazier options in the Personal 3D Viewer or 3D binocular camcorder or 3D cameras. Now with store shelves full of 3D-enabled PlayStation 3 games, so something like this only makes sense. The PlayStation 3D Display is Sony's latest 3D consumer goodie and it's aimed squarely at college dorm rooms. Think of it as the startup kit to suck non-believers into the 3D vortex. So, will it claim you, too?

Mildly put, Sony's HMZ-T1 Personal 3D Viewer that's capable of projecting a virtual 150-inch screen in a pair of goggles is the stuff of every nerd's wildest dreams. In reality, that's all it is: a display. One modder decided he wanted virtual reality, so he gave it some head-tracking abilities.
