If you see this lady turning in clockwise you are using your right brain. 
If you see it the other way, you are using left brain.
Some people do see both ways, but most people see it only one way.

If you try to see it the other way and if you do see, your IQ is above 160 which is almost a genius. Then see if you can make her go one way and then the other by shifting the brain's current.  

BOTH DIRECTIONS CAN BE SEEN This was proved at Yale University, over a
5 year study on the human brain
and it's functions. Only 14% of the US population can see her move both ways
