This video shows street artist David Choe painting the walls of the first Facebook headquarters in 2005. Facebook founder founder and CEO Mark Zuckerberg even has a go with the spray can himself.

Why is this video interesting? And why now? Because Choe is about to become a millionaire thanks to these murals. When Facebook IPO’s in the near-future Choe will find himself sitting on an absolute fortune.

Choe eschewed being paid in cash for this job, choosing instead to take stock options. Zuckerberg was rather generous, giving Choe 3.77 million shares in the company. At $53-per-share that’s a cool $200 million.

This makes the artwork Choe completed on the walls of the Facebook offices some of the most expensive in the world. Certainly in terms of how much was paid at the time it was commissioned.

That’s one lucky guy… and I’m in the wrong job.
