Top ten geek haircuts

Richard Stallman: Open-source beard
Until now, we've concentrated on the best of hair, but not really considered all the facial hair it's possible to grow. Stallman -- considered to be the father of the open-source movement and a hero to many -- is the only real top-notch geek we've discovered who's managed some awesome face fluff.

Stallman didn't have a private residence and lived on campus at MIT for many years, according to Wikipedia, proving that he was the ultimate geek by not wanting to leave their ultra-fast leased line.
