Watch the Spinning Lady...

Freakonomics wants us to know that the human brain works in mysterious ways. Behold the dancing lady, what will she reveal about you? Look closely:

Apparently, it all comes down to what side of the brain you use more. PerthNow explains:
If clockwise, then you use more of the right side of the brain and vice versa.

Most of us would see the dancer turning anti-clockwise though you can try to focus and change the direction; see if you can do it.

Okay, I must admit. I had some rather puzzling results at first. My friend talked me through it:
My friend: Click on the spinning dancer.

Me: Okay, no bull, she changed direction on me a few times! Let me try again…Oh no, wait, I’m right brain. Well, that’s me alright.

My friend: I can only see it go clockwise. She won't change direction on me.

Me: I’m used to it. Most girls change direction on me.
Honestly, when she changed direction on me, it felt like a weird college flashback. So, what brain are you? Do tell, do tell!

I always see her spinning clockwise first, but can easily make her change back and forth by focusing on the foot of the straight leg :)

At first I could only get her to spin clockwise no matter how hard I tried. But then I noticed it depends on what part of the body I focused on. When focusing on her extended leg, she spins clockwise. If I ignore the leg and focus on her shoulders, she begins to go counter-clockwise. I'm definitely a right-brainer, though. Cool test!

Although I can change spin direction, the reflection doesn't seem to correspond to a clockwise spin.

I love this! I'm totally right brained but I'll keep trying.

took me about 30 seconds to get the change in direction going.
had a closer look at it and worked out how it works.
its a matter of perspective.
the image is not 3D and because it is black you cannot tell wether you are
looking at the front or the or the back of the girl,except when she is side on and
when she is side on you cannot tell wether you are looking at her left side or her right side.
so depending on which perspective your brain takes she will spin one way or the other.
change your perspective and you change the direction.
with a bit of practice you can change her direction every half rotation.

She twirled clockwise for me at first glance but could see her change direction by looking at the animation in my peripheral vision, then looking back at her. So does that make me bi-brained?

I wonder if more women are "bi-brained" than men. I don't mean that comment as a snark-attack against men -- research has shown most women can multi-task better than most men so maybe that's related some way and it's an artifact of gender biology.
