It may look fine when your head is practically duct taped to a movie seat staring at an enormous movie screen. but I’d imagine that on a 24" LCD panel, as soon as you change your angle of vision the illusion would be totally ruined.
I don’t think that 3D will take off until we don’t need glasses and can look at it from multiple angles (requiring, possibly a cube that sits in the middle of the room and you can look at the image from all sides). As for 2D displays, the only way I know to make 3D without the use of glasses is via parallax; little geometric prisms or whatever that shoot two pictures at different angles. The 3DS does this…poorly.
At the moment, 3D is a gimmick. I’m not sure if it’ll ever rise beyond gimmick-status…unless there becomes some real world applications such as, I dunno, that holographic display they had in Iron Man 2 where the display can surround you and you can walk around it.
Unfortunately it kinda is taking off. Nvidia has good marketing. And every fucktard in the movie industry seems to want to do it as well as every major tv manufacturer.
