Facial Recognition in Ubuntu

Just set this up on my laptop today, it works a treat, although I didn’t get GDM working.  In the end I decided that I’d rather enter a password than sway back and forth trying to get into the camera’s “zone” – you need your chin pretty much over your keyboard for it to see you.
It’s an awesome thing to set up and see running though.  I totally recommend it, it also works with su, sudo and screensaver.  Anything PAM authenticates.
I’ll try a super-paranoid mode for a while that needs face, fingerprint and password, just for kicks.
It’s a Google Summer of Code thing, so you know you’ll love it
