clockwise : counterclockwise

The 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.
