Optical treats for the eyes

It's an animated GIF but the page isn't undulating - only the dots are moving around the circles.

It's a classic - three legs or two?

It's not animated, but stare long enough and the circles appear to rotate.

Actually, the lines are all parallel

It's not animated, though things may appear to move.

The orange circles are the same size.
