Hehe, good shit that

I've only come across this now.
At first I could see her only spinning clockwise, then something clicked and I could see anticlockwise and after a little staring I figured out the way to make her change directions every half turn. Here's how to do it:
If she's spinning clockwise wait for the moment when her raised leg is at 6, then quickly direct your eyes at 7. She'll change the direction. The other direction: wait until it's at 6, then shift your eyes to 5. She'll change again.
After a while you'll not only be able to switch it every half turn but you'll find it difficult to let her do even one full turn. Just look up then. Yeah, she's got great legs, but her upper body is fucking great too!
Let me know if my method has worked for you.
peace out
