Whereas "Nerdgasm" is a bit more fun, this one is actually rather sweet. It's called "Geeks in love," and it's a serenade for nerds. (Who else will sing in binary?) It's on Rock, Paper, Cynic, which is one of my favorite webcomics. I haven't really taken the time to listen to all of his music, but this one itself is awesome.
