Either way, perhaps @AkiyoshiKitaoka can explain why it is doing what it’s doing. It works the same way regardless of the orientation, so it must have to do with the rotation direction alone. But why?https://twitter.com/jagarikin/status/1229954803603689473 …

This illusory motion is induced by luminance changes of areas. The way is shown in the attached image. Kitaoka, A. (2006).

I believe Stuart Anstis proposed this phenomenon first. Anstis S M, 1970 "Phi movement as a subtraction process'' Vision Research,10, 1411-1430 Anstis S M, Rogers B J, 1975 "Illusory reversal of visual depth and movement during changes of contrast' 'Vision Research159, 57-96

But many researchers prefer to cite Richard Gregory. Gregory R L, Heard P F, 1983 "Visual dissociations of movement, position, and stereo depth" Quarterly Journal of Experimental Psychology, A, 352, 17-23.
