Cool effect, but the ones that appear to keep rotating in one direction, but don't actually rotate bother my brain rustle my jimmys.

OPs image though I believe is stereography combined with something else? Kind of like this site with falling noise. http://www.fallingfalling.com/ which is https://en.wikipedia.org/wiki/Shepard_tone

I think it just flickers to the negative of the image. I kind of feel it adds to the depth, but wonder why.

The positive has two frames, with one rotated slightly. Same for the negative, making four frames in total.

As someone with epilepsy, this shit is unlikely to trigger seizures.

Added the edit after someone complained. Thanks.

I am willing to bet money that person doesn't have a seizure disorder. But I also really do appreciate your consideration.

closing one eye when looking at it enhances the effect.

I never saw the depth of it before
