There is a new tweak available in the Cydia Store for your iPhone or iPad Touch that gives your springboard a 3D effect without the need of 3D glasses. It's only $2.99 for the tweak, which is a small price to pay seeing how they charge you up to $5 at the movies for the 3D glasses!
The reason this sort of effect works: True 3D doesn’t need to be binocular. When you close one eye, you only see one image, yet you can still perceive depth. You can’t "see" the depth as you can with 2 eyes, but with motion, and in-brain calculations, you can still understand the depth. On a flat, 2D screen, with flat, 2D images, you don’t get depth perception because the small motions of your head don’t change the angle in relation to the image. This type of effect (better than using cameras for eye tracking because its slow, though i’m looking into that) works because it allows perspective changing based on motion/relation to screen. To be honest, holding it in hand, it looks "better" when closing one eye, basically forcing your brain into "single eye depth calculation" mode, in which motion changes register as depth, giving the effect.
