3D without glasses OMG!
Today I discovered Jim Gasperini's Stereo Photography. I don't know if he discovered this technique, but the simplicity astounds me. All it involves is continuously flipping between the left and right eyed view of a 3d photograph to give an illusion of depth without any glasses. Simply awesome.

the same z-depth illusion as people see movies...but, nice work

Holy cool! Perry where are you? Thanks for the 3D inspiration!

It's really just a form of motion parallax and yes it's cool. In the old days we did it by flipping back and forth between two slide projectors. If anyone can be said to have "invented" it, it would have to be Ken Jacobs with his Nervous System performances.
Apparently even pigeons do it.

What is this technique of flipping between the two images called?

Jim took an amazing picture of me a few years ago that still makes me smile every time I see it. He's an extraordinary person....I took his set of stereos from the San Diego Zoo with me to Thailand this fall and the kids there LOVED it!

This is nothing special really. The matrix did this to a much larger extent with its bullet-time sequences (taking 360 degrees of still photography at the same time, then sequencing the images).
I prefer the cross-eyed method for glasses-less 3D
