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.
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 Some found that they can make the direction change by looking to the left of the picture and watching with peripheral vision.
it rotates both ways but it is not easy to control it. also, sound some time does this to me too. one pattern for a while and then another pattern, also related to different sides of brain?
