Optical illusions
you can download.
Pure-pixel illusions that work on almost any screen, because the trick is in your eyes: still circles that seem to turn, a photo your eyes recolour, and a triangle that can't exist.

How they work
- Rotating snakes: the black, dark, white, light order fools side vision into seeing motion.
- Afterimage: staring tires your colour cells, so grey looks like the opposite colours.
- Impossible triangle: three real bars lined up so the far end hides behind the near one.
