Is the dancer turning clockwise or anti-clockwise?

At first glance the spinning lady appears to be circling in a clockwise motion.But if you look at the spinning dancer long enough - the lady will appear to change direction and start spinning counter-clockwise.To help swithing, look at her shadow and picture it going counter-clockwise or clockwise.

If you see clockwise, you use right brain more than left; if anti-clockwise, you're more left than right; and most people see anti-clockwise.
