Okay I think I've figured it out. Concentrate on the shadow of the foot, think left, or right, and it will start spinning in that direction. I found
this to be a good work out for your brain, you can almost feel that side of your brain working to get the picture spinning the other way.
If you take your focus on the picture off, and move your eyes to the very far top right corner screen, or left, you'll notice it spin in other way
w/out focusing.
You can change the direction of it by looking at the foot and imagining what it looks like the other way. Use to play with this awhile back ago. Still
interesting...
Ahh yes, that means you use the left part of the brain and are more logical. Logic dictates to turn the lights on the spinning woman.
I showed this to my best friend, he could not concentrate and get her to spin the other way. For the 13 years I've known him, he has always been
creative. I'll have to show this to more people, my interest has been aroused.
I cannot see it otherwise. the up and down matched with the spin ... I just can't force it, and I usually can with most other things ... unless
this site has corrupted my brain
