"Slavisa Pesci claims to have discovered new images in the 15th mural in the dining hall of Milan's Santa Maria delle Grazie church by superimposing a reverse image on the original image.

When doing so, Pesci said he observed, for example, that the two figures on either end of the long table appear to become knights, and that another figure appears to be holding an infant."

Oh look in the sky, that cloud looks like a bunny rabbit.

"If this computer analyst did not make a historic discovery, I hope he created something artistically beautiful."

:)

For me it's just an hoax
