I concur. I use logic but I can only see her moving clockwise. When she is facing you her right leg is sticking out. So obviously that never changes and it actually moves from left to right. Therefore Clockwise. Logic + right brain = win.
Same happened witth me.
Edit: I removed the shadow-thing, I was posting to fast for mysefl ^^.
But ye. I see her spinning clockwise and the thing Megadoomer said.
The trippy thing is that its a .gif and your mind is able to flip its direction. Not just the direction, but the whole image gets flipped. And for the people that say they see the legs go a different direction than the torso, why does that happen?
