I *kind of* get how it works, but its not the easiest thing to explain. Her spinning is real, but what you see kind of isn't. You see a definite image of a woman till she turns sideways, that's when the arm and leg sticking out blend in with the rest of the body, creating no definite distinction between one extremity from the other. This is when the direction change happens most of the time. This is all i was able to come up with though, most of it is still pretty confusing to me. Glad you guys like it :D
