I got intrigued with Warhol after I found out he'd supported the Velvet Underground and suggested they work with Nico. It was a strange suggestion, but the results were brilliant.
I'm also really interested in his "Factory" idea, basically a very wild art studio. It reminds me a bit of Erdős, Grothendieck's seminars, and hackerspaces all at the same time. Basically, get a bunch of talented people with very different skills and perspectives in the same place, with a bunch of stuff to work with, add drugs, and see what happens.
