Mike Link is a Super-geek

Mike Link (the guy on the right)

and this guy (also on the right), built their own controller for Frets On Fire, an open-source Guitar Hero clone for Windows out of PVC pipe, old keyboards, and duct-tape.

It's freakin' sweet, although since the keys are 1/4 inch strips of metal, it also hurts like hell to play.

As if that wasn't enough nerdiness, he has also got it tied into the lights in his room, so they change with the music.

Awesome.
