Ooh, it does not for me. It is static.
Very odd. It rotates like crazy for me as soon as I move focus, but my wife claims not to see any motion at all. Weird evolution at work.
I am red & green colour blind, not sure if that plays into it.
Certainly does for me: it the rotsnake colour scheme, right? But the movement is continuous: in the red-purple one, it jumps in steps.
Color is indispensable. It seems color enhances this type of illusion to some extent.pic.twitter.com/37cRI78WuW
They move at the same speed in the same direction for me.
Interesting: the rotsnake (3x2 circles) one has some which rotate clockwise & others counter-clockwise (the circles are different).
The direction of illusion motion is constant (Type IIa).pic.twitter.com/cZTkciUpnF
That's helpful. But to be clear, in the 3x2 panel (colour or monochrome), the circles rotate CC, C, CC (top), & C, CC, C (bottom), right?
