The Jesus 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.
