Are you left brained or right brained. If she's spinning clockwise, you are right brained and left brained if she's spinning counter-clockwise. If you can get her to do both, you are equally balanced...

Very cool! We each saw her going a different way. What does that say about us? 
I saw her going both ways. Does that make her or me bi? LOL
Here's another one. You guys remember these Stereograms that were popular in the 90's??? This one is animated. You should see a shark swimming, facing left. A good way to get it, if you have trouble, is to lean in close to your monitor (irradiating yourself) until your eyes blue then slowly move away, whilst trying to maintain the blur.

Cross eyed is the easiest way to see them although there are inverted. No, not perverted! 
I can't do the cross-eyed technique. It gives me a headache.
Guess I am brain damaged because when I stare at her shadow she changes directions.
No matter what I do or when I check it, she spinds clockwise.
You can also make her change direction by looking away enough that you only see her in your peripheral vision and imagine her spinning the other way, then look back. That method works best for me.

Haha...cool stuff Don
I didn't freak out! The girl just kept going clockwise, then counter-clockwise and I thought I was having issues. Thats all....

She goes both ways for me, like she is dancing. Maybe because I like it both ways. She only goes one way for Jay.
HAHAHAHA ROB! You're girl just told us how it is. LOL! That was priceless man. If anyone could cut your balls off, it's your lady. That illusions seems impossible I kept thinking how the hell am I not seeing her chin and arms spinning the other way. It seems to defy logic. It's one of the cooler optical illusions I've found.
