This is completely insane. If you see this woman moving clockwise you are apparently right-brained. If you see her moving anti-clockwise, you are left-brained. For the record, I could not, simply could not, understand how anyone would see her moving clockwise. But you can "trick" yourself by, well, I don't want to tell you. The point is you can make her look like she's going the opposite way from how you first saw her. In any event go check it out, it's fun!
