Lines or Jesus Illusion ?

There is a Jesus face in this image,You might need to stare at the lines for a few minutes, but after a little while you’ll begin to see the outline of a figure. I found it helpful to actually step away from the monitor to really see the image pop out or just close your eyes a bit in front of monitor.

Obviously, this is an optical illusion. But it was also an entry in some sort of design competition or an ad or something. If anyone knows more about where this came from please share with the rest of us.
