Paul sent this to me. Click on the image to go to the the post at Perth Now. The claim is that it shows your brain hemisphere dominance. If she appears to spin counter clockwise you have left brain dominance. Clockwise is right brain.
My initial response is counter. I can switch to clockwise buy looking at her standing foot. Then it is difficult to get her to spin counter clockwise but I can do it by looking at the shadow.

This is pretty cool!
Strongly clockwise. I have to really look away and blink my eyes a few times to start seeing her spin counter.
Leisa:
I must be a bit strange … I see her going clockwise, then she stops and goes counterclockwise … then she stops and goes clockwise again.

Okay, Leisa and Paul, this is amazing. As a bodyworker, I love watching animation and still figures. I was just looking at the woman’s image, turning clockwise, then read the details. When I looked back upafter reading, she was turning counter clockwise. My thought was, oh, the spin changed direction when I looked away. I played with the process, looking at her foot, her shadow, her body. It was truly amazing when I’d get stuck in counter clockwise spin, and I would have a hard time seeing her in clockwise rotation again.
Then I brought my husband in to look it – tripped him out, too.
This was a very interesting exercise.
I’m visiually impaired, and seeing is more of a brain function thing (filling in missing information) than what I think folks with normal sight have – depending on their eyes and visual accuity. I often notice things that those with perfect vision miss, because I’m more observant by necessity and force of habit. My common response is to shake my head and say “oh, you sighted people.”
Interesting.

Wow, I’m intrigued! I can *only* see her rotating clockwise. I absolutely cannot see her any other way – she’s moving “en dehors” as it’s called in ballet. I’m totally stealing this and blogging it
but I’ll reference you, I promise!
