These rows are perfectly horizontal and are not moving. A mind-bending anomalous motion variation of the Café wall illusion by Akiyoshi Kitaoka.

Image transcription: Rows of black and white zigzag patterns forming 2x2 checkerboards on a grey background create an optical illusion of warping and motion.

Wow… And if you really want to see something crazy, scroll it up and down…
Thats what i thought this was about as i don’t see anything special when it is still. Am i doing something wrong ?
So if they don’t move for me does that mean I’m dead inside?
Whoa that’s making ne nauseous 😳
If you get out an image editor and compare where the pixels fade to the background grey, they are nearly, but not pixel perfect to the same height on the peaks of each row. Different peaks come to different heights. The darker shaded top left ones come up 2 pixels higher than the light ones.
Saying they’re perfectly horizontal is slightly misleading. A sawtooth wave on a oscilloscope is perfectly horizontal also. Technically correct, but also omitting some key detail.I can make them dance to music!
I look at any one top or bottom edge and see it’s level… but every thing less is slanted.
Arrrgh and they bobble…Does it mean anything if they aren’t moving for me, unless I scroll the image up and down? I’ve been told that I have field independent vision: I see parts before the whole.

Interesting, after seeing the comments about how it works for people I can make it hold still or move. It’s wild!
The illusion when moving it up and down does not even break when the picture is very out of focus and viewed with one eye. So there must be something fundamental about the rough shapes and/or color grading. All the fine details are irrelevant.
