The rotating snake–wha?

Are you seeing motion? Is it going inward or outwards? Are you sure?

This is a good illusion, called the rotating snake, and it depends on the relative brightness and width of the stripes. For the full explanation and a graphic you can play with, see Michael Bach’s site. Way cool, and the illusion repository Michelle asked about.
