This is a very famous and quite haunting illusion that works amazingly well. Stare at the four dots in the centre of the negative image for a minute or so. Now close your eyes. It works better if you have light facing you.
The face of Jesus, inside a white circle, will suddenly appear beneath your eyelids. The face is not the same negative of the original image, but an accurate face. Your brain cleverly reverses the negative image and the result is quite stunning. Jesus appears and stays a while, his pale face surrounded by his long dark hair.
The Face of Jesus
Stare at the four black dots in the center
of the image for 60 seconds. Then quickly close your eyes,
while facing a lamp of a bright window. With your eyes closed,
you will see a white circle with the face of Jesus inside it.
