Via Former Pawn, I read about this profoundly-obvious study regarding artists and their income. However, the sidebar of that page led me to this discussion of the obscure connection between George Lucas and Canadian experimental filmmaker Arthur Lipsett:
That’s right–Princess Leia’s cell was named after an obscure film made by an avant-garde filmmaker from Montreal. Lucas included the detail as an homage to 21-87, which made a deep impression on him when he saw it as a film student at the University of Southern California, before he became a director and founder of the Lucasfilm movie empire.
Wow. That’s even more obscure than the Wilhelm scream.

I’d like to know what the median income for artists is.
