The Jesus Optical Illusion is a popular afterimage illusion.  Stare at the dots in the center of this image for approximately 60 seconds.  When the time is up, quickly close your eyes and look at a bright light source (like a lamp).  Alternatively, you can also look at a blank wall.   You should see a white circle with an image inside of it.

What did you see?

If you can get it working properly, you should see an image of Jesus.  That certainly makes this a very powerful optical illusion!
