This is a Right Brain vs Left Brain test. Do you see the dancer turning clockwise or anti-clockwise?

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. Personally I tried it and I can switch back between clock wise and anti clock wise. I focus on the feet and the shadow to do that.
