Jesus Illusion Explained

anyone who can explain about this? http://www.eyetricks.com/jesus.htm?

i am really curious about that optical illusion. can you explain it?

I saw Jesus!!!… When you focus on something dark, then you look into something bright you can see a picture. Since the black markings (if you use your imagination) slightly look like Jesus, when you look at something bright (light still goes through your eyelids) you can see the dark shape against the light…
