Barber Pole illusion - Optical Illusion

The Barber pole illusion is a visual illusion that reveals biases in the processing of visual motion in the human brain. When a diagonally-striped pole is rotated around its vertical axis (horizontally), it appears as though the stripes are moving in the direction of its vertical axis downwards.
