The Spinning Dancer Illusion

With the Spinning Dancer Illusion, the dancer appears to sometimes spin clockwise and then sometimes shift to spinning counter-clockwise.

At first you might only see the dancer spinning in one direction, but at some point your vision will shift and you will begin to see the dancer spin in the other direction. When that happens, it’s truly startling.

The Spinning Dancer Illusion relies on ambiguous clues (the shadowy dancer) and our two-eyed depth vision.
