By now, you've no doubt heard about Facebook's IPO (intial public offering, or in lay parlance, going public.)

How big is this thing going to be? Well, put it this way: way back in the dim dark past of 2005, an artist was commissioned to paint a mural for the company headquarters.

Since Facebook hadn't even really become a national phenomenon beyond college campuses yet, CEO Mark Zuckerberg offered the artist, local graffititian David Choe, the ludicrous option of stock options instead of cash. Two-tenths of one percent of the available shares.

Those options could be worth $200 million at execution, meaning the company could be valued as high as $100 billion dollars.

$100 billion dollars. For a company that produces nothing, and merely provides a place where you, the user can upload your creativity.

Where our share, Mark?
