Do you see it spinning clockwise or  counter-clockwise? I see it spinning counter-clockwise, but i was able  to switch it in the other direction, its hard for many people. Give it a  try. The spinning girl is a form of the more general spinning silhouette  illusion. The image is not objectively “spinning” in one direction or  the other. It is a two-dimensional image that is simply shifting back  and forth. But our brains did not evolve to interpret two-dimensional  representations of the world but the actual three-dimensional world. So  our visual processing assumes we are looking at a 3-D image and is uses  clues to interpret it as such. Or, without adequate clues it may just  arbitrarily decide a best fit – spinning clockwise or counterclockwise.  And once this fit is chosen, the illusion is complete – we see a 3-D  spinning image. By looking around the image, focusing on the shadow or some other  part, you may force your visual system to reconstruct the image and it  may choose the opposite direction, and suddenly the image will spin in  the opposite direction.</blockquote>
