I think the colored segments are rotating at different rates.
Because of that, when they sync up in certain ways, like when we see the blue section of one circle overtaking the blue section of the other circle, our brains interpret that as the circles getting closer together rather than “this circle has a higher angular velocity”. If one blue section is receding from another, our brains figure the circles must be moving apart.
I’m not sure the arrows cause any part of the illusion. When I covered them with my fingers, the circles still seemed to be moving around.
Anyone else?
