This has been going around for a week. There is an article
about it. If you see her turn clock-wise, then you use more of your right brain; otherwise, you're a left brain person. Your left brain is in charge of logic, math, analytics, practical, etc. Your right brain is in charge of creativity, art, feeling, fantasy, risk, etc. And most people I know have been able to rotate the direction with some concentration and luck.
On most personality tests, I score right in the middle. So I first thought that I will not see her rotate at all. But I guess I'm more of a right brain person according to this. I wonder if it'll change from week to week.
