    The direction you first see is whatever happens to be the direction when you first open the link
    I think you're both wrong. The motion of the figure doesn't change, but your perception of the rotation does. The shorter shadow always starts on the right and ends on the left. What changes is your interpretation of which leg's shadow is closer to you.

    As soon as I saw you had replied to this thread, I knew what you had written before I even read it.

    I've tried all the things people have said through out the thread, but I still see counterclockwise, and just counterclockwise.

    Nah nah nah if it was optical, some aspect of the figure would not change in appearance and there is none. When in one direction the arms and legs are in one position, when it flips, the body parts reverse into different positions.

    Then how do you explain the people who can only see one direction, and always the same direction, no matter how hard they try? If it did indeed simply change directions as you claim, it wouldn't really be a brain testing optical illusion and wouldn't be part of that website. But that's not what I base my opinion on - I base it on careful scrutiny of the figure (not an unpleasant task, I might add ).

    Think about it. If you look at a silhouette of a person standing facing to your right with both arms held out in front of it, and one arm is raised and the other is lowered, you can't tell which arm is raised or lowered. If you perceive the raised arm as closer to you, then it's the right arm; if you perceive the raised arm as further away from you, then it's the left arm. The figure hasn't changed, or even moved, but you can see the raised arm as either right or left. That's what is happening with the spinning lady.
