Spinning Dancers Optical Illusion
You might recall the Spinning Lady Optical Illusion where a woman spins continuously and seems to flip-flop back and forth between a clockwise and counter-clockwise direction. This video, based on the same concept, presents two silhouettes of ambiguous spinning dancers on the left and right. As the dancer in the middle moves clockwise, the two silhouettes also seem to move clockwise. When the center dancer begins moving the opposite direction, it appears that the silhouettes do the exact same thing.
