The reason that the circles seem to rotate is that different wavelengths of light hit your eyes at slightly different angles. If you will notice that the circles going yellow-black-blue-white all go clockwise, while all the circles going blue-black-yellow-white all seem to be going counterclockwise.
Also you’ll notice that if you look directly at a circle that it seems to almost stop moving. This is because when you look directly at the images, the angle that the different colors hit your eyes isn’t as noticeable as when they come in from the side.
You’ll also notice if you download the image and make it into a grayscale image that the circles continue to rotate. This is because it’s the contrast in the colors and not so much the colors them selves that make it rotate.
As for why when it is shrunk down it stops rotating, this is because much of the detail is lost. Notice that even when it is enlarged the centers seem to move slower than the outsides of the circles. This is because it starts to get small enough that the wavelengths start to merge together.
Anyways, I bet you didn’t expect a headless cow monster to know that now did you?
