"Hebi rokujukkyodai"*

*Hebi = snakes, rokuju = sixty, kyodai = brothers

Although each line made of snake's mouths is horizontal, the uppermost one appears to tilt counterclockwise, and the next one clockwise, and so on. This tilt illusion is the Fraser illusion. In addition, each row appears to sway horizontally.
