I dunno if this is just my mind playing tricks on me or what not, but I tried an experiment:

1. looked at the dancer
2. Started reading the text from the adds on the side of the page, while still watching the dancer in my peripheral vision.
3. Watched to see if she started to spin counter-clockwise.
4. She did.
5. Observed the pictures on the page and the different colors in the pictures, while still watching the dancer.
6. She began turning clock-wise


So it seemed when I was reading and using my left side, she went one way, and when I was observing the colours of the pictures, she turned the other, since I was using my right.

Like I said... could just be all mind games but an interesting experiment at that.
