Cool stereographic effect

This guy has taken a bunch of pictures of the same scene from two slightly different angles. He then swaps the two images several times a second to create a surprisingly effective stereographic effect without any sort of glasses or crosseyed tricks:

Warning: While the link itself is SFW, some of the sub pages are NSFW.

It works much better on some images than others, but on the ones that it works on, the image really looks 3D. It works by tricking the brain into thinking it is seeing both images, even though the images only switch a few times a second.

A strange side-effect is that the images even look 3D through one eye, which is just a strange feeling, when the image on the screen looks 3D, but the room you're sitting in doesn't (since one eye is closed).
