Which way is she spinning, clockwise or counter-clockwise?Once you perceive her going one direction, it's hard to switch, but possible. Then, once you see that--it can be just as hard to switch back! Pretty amazing, since it looks like she suddenly changes directions!
If clockwise, then you use more of the right side of your brain. If counter-clockwise, more of the left side.
The majority of people see the dancer turning counter-clockwise. This test is originally from Perth Now:

Last night, exhausted, I saw her turning counter-clockwise, but I could switch her back and forth easily. This morning, relatively rested, she is turning clockwise and I can't switch her back. I wonder if mood and other such matters make a difference?
