Here's an optical illusion of a girl spinning. Some people will see the girl spinning clockwise. While some will see it naturally spinning counter-clockwise. See if you can get the girl to spin the opposite direction. It's very difficult! Try by covering all of the girl except a small portion of her legs with your hands, and then try your hardest to envision her spinning the other direction. The illusion has nothing to do with right brain or left brain thinking although you may hear otherwise
