The ballerina illusion

No matter how hard I try, I cannot get the spinning dancer illusion to flip. Looks like someone has found a much more powerful version of the illusion:

What I especially like about this version of the illusion is I can totally get why it is happening. There aren’t great depth cues so there is a powerful prior that if you can see a face then that face is looking in your direction – hence direction flipping.

  1. Now I have the problem where I can’t see a full rotation. The image just spins to the right then left then right then left. Just as bad. I want true bi-stability with unpredictable flipping.
