Saw this first through Digg.com at http://www.voltier.com/stereo/ and have been analyzing the interesting part of the illusion. The below image or animation is generated from two 2D images.

You should be able to easily see it in 3D perspective especially with the water splashed up.
If you don't see it please wait, it must be loading.. the image is 180kb

My understanding:
The effect is created by fastly swapping images taken at 2 angles from the subject.. or two perspectives of the view. Because your vision can remember an image seen for a fraction of a second, by the time the image is swapped.. your brain overlaps the new image with the image still in memory and gives you a feel of two sides of some portions on the image.. like the water droplets splashed up.

In effect you see more of a droplet than what you would see if you were seeing one of the 2D photos. So, it gives you a 3D feel. The 3D effect is not because of the shake.. the shake is just because it is an animation with more than required time between slides.

3D is about being able to see the 3rd dimension or the depth of an object to visualize it separate from the rest of what is seen.

The above concept is probably how our eye sight works, and so having two eyes may be too important for vision. With one of the eyes closed, we may be seeing things in 2D but still not realize the loss much.

I think I have heard about this concept long back... I can remember reading something similar in some journal about a 3D system being developed which could allow delivering 3D images on a normal LCD monitor itself, and probably technologists are at it already in using this same concept to create future 3D television and cameras.

I can imagine cameras having two lenses instead of one as it is now, and the images streamed properly to a monitor with both perspectives swapped at an optimum speed, to produce clean, non-shaky 3D for TV. What do you think?
