Still think 3D is cool? Then you'll definitely like this iPhone app, TwinShot 3D, which uses your iPhone's camera to shoot your photos in 3D.
TwinShot is $2, and apparently has you take two shots, then mixes it into the final 3D version.
This also means you'll need some hot 3D glasses to see the image in 3D afterward, or you can just admire the distorted-color photo — which I actually personally enjoy. Now stop staring at the picture before you get a 3D hangover!
