The Spinning Dancer Spins ?

This is a cool optical illusion my brother showed me: http://greengabbro.net/2007/10/20/th...and-the-brain/ (could be welcome to last week, new to me). Which way does is spin for you?

There are some other moves I'd like to see that dancer make . . .

That's trippy, the reason it works is that there is no specified outside leg because it's a silhouette. You can interpret it either way.

I'll bet your view of it coordinates with your dominant eye (typically the eye with better vision).

If you blur your vision and force it to spin the other way and then slowly come into focus you can change the rotation.

For me, when I look at it, I "naturally" see her spinning to the right. If I close my eyes, I can easily "imagine" spinning either way.

That's really crazy. At first all I could see was counter-clockwise until I did the whole unfocused/blurred vision thing then all I could see was clockwise!
