If you keep you eye on one of the balls the other one seems to be all over the place. Then try it with the other ball.
This is our take on the famous Lilac Chaser by Jeremy Hilton. We have changed the colors and added another ball going in the opposite direction. Just stare intently at the center cross.

In Lowry's Returning from Work, we see the industrial landscape and 'matchstick' figures typical of the artist, with bent figures appearing immobilised and struck down in the art of fixation.
However, this illusion changes all that as the figures seemingly start to shuffle along!
In reality, the characters are moving backwards and forwards and only seem to shuffle because a perceptual bias has been created that favours seeing the small forward movement. This appears much larger to the viewer who, in a way similar to how we navigate through crowds using just passing glances, unconsciously extrapolates the movement forward.
The star in this animation does not change color at any time.

This wibbly wobbly pattern is not really wobbling at all. It is only moving downwards the rest is caused by your eyes. If you just lock your eyes on to one green ball and follow it down the page you will see there is no sideways movement.
