Right and Left

Take a moment and visit this website. When you get there, don't think, just look: which way is the dancer turning?

The fascinating thing here is that this optical illusion actually measures (or at least claims to) which side of the brain is dominant for you. I fall into the right brain camp; the second I look at this image, she's moving clockwise. The article claims that most people see her moving counter-clockwise (or "anti-clockwise," as the article is Australian), and that most people are left-brainers. Showing it to people around the office, that seems to be true so far...

It's fun; stare at her shadow for a second or two, and you can make her switch directions. I've gotten pretty good at it...
