the image is legit, i can change it back and forth at will now, it all about if you think her left leg is on the floor or the right leg, left leg she spins clokcwise, right then she goes counter clockwise, this is tight, when i make my mind switch back and forth fast enough, she doesnt even go in a circle, shes just goes back anf forth.
heres a tip, cover the girls upperbody with your hand so you can only see her two feet, now just decide which way you want her legs to be spinning, slowly move your hand up and voila.
