That's interesting--normally on this kind of image, I default to one way, but with effort can make it spin the other way. But this one doesn't look like it's going in circles to me--as soon as her face goes backward, my brain says "I know I can't see through the backs of people's heads," and she's instantly forward-facing and going the other way. She just goes left-to-right, right-to-left, never all the way around.
