      "Rotating snakes": It is supposed that disks appear to rotate clockwise in this image (though it is also supposed that the illusion is weak when seen in the central vision).pic.twitter.com/2RVxrvR1Zc

          Wherever I look there's no motion but some vibe.

          The speed of both discs is increased (clockwise) when my centre of focus is directed away from *both* discs. ie, rotation is stronger when seen in non-foveal field.

          I see slow clockwise rotation in the figure that I’m not looking at. If I look in the centre I see no rotation.

          Spins CW but only when not looking at it directly. The motion also doesn't travel a full circle, but is pulsing.
