if u save the file, and put it in paint, and invert the colors, jesus comes up on the pic. So when you look at the white wall they invert and bam, jesus himself.
the reason it works so well is that the non inverted picture resembles a face making it very hard for your brain to see through that and pic up the resembles to jesus in the picture. but when its inverted the white creates a backround instead of being part of the picture. allowing you to see the jesus face.
the weird thing is, my dad didnt even have to look at it, he saw it in the pic right wen i showed it to him, the original one that is, no idea how he saw it but he did, scary stuff
