Well this link say's it all try turning the dancer from clockwise to counterclockwise. Usually they say when it's turning clockwise you're using mostly you're right part of the brain (right hemisphere) and when she turns clockwise then i guess you're using the left part of the brain (left hemisphere) It's something interesting to watch to free some of the bordness lol
