Michelangelo Buonarroti - known by his first name the world over as the singular artistic genius, sculptor and architect - was also an anatomist, asecret he concealed by destroying almost all of his anatomical sketchesand notes. Now, 500 years after he drew them, his hidden anatomical illustrations have been found-painted on the ceiling of the Sistine Chapel. - R. Douglas Fields @ Scientific American
Looks like a stretch to me. I think they're looking at the various shadows and forms in Michelangelo's work like most people try to find images when they look at clouds.
