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. THIS IS NOT A JOKE. BOTH DIRECTIONS CAN BE SEEN.
So which direction is the lady turning?
