I didn't know that this kind of parallax flicker can get picked up as depth. Even works with one eye shut. Some of the images made from stereoscope slides could have used a lower rate of flicker, though. Those slides were taken with more than a face's worth of distance between the lenses, and fast flicker doesn't work for them somehow.
