I've spent the last two years training my brain to switch directions at will. I have yet to master this skill, but when I do, I will become a true magician.
She's spinning whatever direction I damn well want her to. She's a woman, she does as she's told.
Not this again.
Wow, that is an impressive.

That said, I can't vote for either choice, as the answer is that she's two-dimensional. That she even appears to be "spinning" at all is an optical illusion.

Using this principle, the artist has made very good use of the ambiguous nature of silhouettes so she could appear to be spinning in either direction.

The illusion is perhaps the most vulnerable if you look at the point of the extended foot. It contorts weirdly as it nears the center because it can't be both the furthest and closest point while maintaining the same size, and other leg's silhouette isn't thick enough to obscure this in the same way the body's does the hand.
I have to stare at the right one longer than the left one to make her "spin" the other direction...
It's cool. I stare at the center look left blink she's spinning like that one, stare at the center look right and she's spinning like that one. Amazing.
Wow o.o
To me, she always looked like she was facing forward and changing her rotation as soon as her foot reached the furthest point.
Looking at left: left and middle are going clockwise.
Looking at right: right and middle are going counterclockwise.
Why didn't you include an option for neither? That kinda stacks the results.

Yeah, I should have, a bit too hasty to get something so awesome on my blog...

I could add a political jab here, but I won't.

The hard part is to look at either left and right and make the middle one rotate in the opposite direction without looking at the other one ;)
If I shift my view to the other leg at just the right time, I can make it look like the leg is being swung out forward, which is interesting because the leg isn't being swung out forward in either rotation but rather is being trailed from behind on both.

It's a poll where the only way to win is not to play, so the poll's actual purpose is to see how many people were successfully tricked.

Go ahead. I dare you.

try to ignore the lines and they´ll rotate in the same diraction, or let them swing their legs from left to right and backwards...

There is actually a right answer. You can tell with this frame right here
