I don't fucking get this, I cover the fucking middle up with my fingers so I can't see the arrows and i still see the circles move, expand and shrink.

i stared at it for a while and enlarged the thing so it was 10x bigger. they actually expand and shrink but it's instant when the arrows change. The outter most and inner most get a thin circle that spins at a different rate, and that tricks the eye into seeing it move in one direction or another. The arrow in the center doesn't actually affect the 'illusion'

im on mobile but i zoomed in really close on several parts and it seems like it doesnt move if you pick an edge to watch
maybe i need to zoom closer on pc

Just blott out the centers of the circles, the illusion will still happen.
