A demonstration of the lilac chaser optical illusion, also known as the pacman illusion. When one stares at the cross in the center of the image for 10–20 seconds, two effects will appear in order: One, the moving empty space between dots will appear as a green dot. Two, the moving green dot will appear to wipe out the purple dots, until only the green dot is visible. A separate effect appears if the eyes move away from the center, showing a ring of green dots.
