Burger Grease Artist

In 2009, Arby's commissioned artist Phil Hansen to paint a version of the Mona Lisa using grease from the burgers of 14 of their competitors. He called his creation Mona Greasa.




Another curious fact about Hansen. According to wikipedia, while in high school he managed to cause himself nerve damage because of his obsession with pointillism.

He's also written a book that sounds interesting: Tattoo a Banana: And Other Ways to Turn Anything and Everything Into Art
