Sylvester Stallone and Marilyn Manson
The Worth1000 website is always an interesting waste of time for me. It's a site of Photoshop contests, where artists try and out manipulate, blur, cut, transform, and paste each other. It's people using computer software to change pictures for those that don't know what Photoshop is.
One of their regular contests is called "Modern Renaissance" which asks contestants to put the celebrities of today into old paintings.

Here's Rocky (Sylvester Stallone) painted by Rembrandt.

And Leonardo da Vinci did another version of the Mona Lisa, with Marilyn Manson as the sitter.
See all the entrant over at
