The Facebook IPO is bound to create over 1,000 millionaires. It's not only the co-founders who are all billionaires now, or the early investors, which have made a killing on Facebook, or even early employees that were granted stock options, it's all sorts of people that managed to get even a small piece of Facebook early on, like graffiti artist David Choe.
He was commissioned to paint some of the walls at the first Facebook headquarters and is responsible somewhat for Facebook's distinctive interior design "look."
At the time, Facebook was still small and Zuckerberg offered him either a few thousands of dollars, or a stake in the company. He chose the latter, even though he thought the site was "ridiculous and pointless."
He is now set to become $200 million richer after the IPO, if he hasn't sold some of shares so far. He also recently painted the new Facebook headquarters, you can
