Optical Illusions That Will Mess With Your Mind

Lilac Chaser

This visual illusion consists of 12 lilac dots separated like the numbers on a clock, with a black cross in the middle. Each dot is blotted out briefly, for 0.1 seconds, in a clockwise rotation. If you stare at the cross, the movement of the disks is replaced by a green dot, and gaps appear throughout the circle.
