What's your favorite programming language, and the project you are most proud of that you built with it?

I'm just enough of a polyglot to not have a favorite. My current front runners would be Ruby and Clojure, and I hate each for not being the other.
As far as pride goes, you'd have to go pretty far down the list before finding something that isn't VimL. I'm not even sure what it would be.
