When Facebook wanted some graffiti art for its walls seven years ago, they hired David Choe. At the time he was still relatively unknown. Today he is huge. Back then, the company offered to pay him a few thousand dollars for his work or take Facebook shares. Choe thought the company was ridiculous but took the shares. Now he is set to make $200M for his decision. That is some crazy money. He is really, really good, but $200M? To his credit, Choe will not talk about his shares and will only talk about his work.
