At Twitter, one of the projects I work on outside of my normal day-to-day duties is called Twitter Baseline (previously Twitter Blueprint). It's a CSS framework that allows our developers to make any project "Twittery." We've been using it internally and in various forms on some public sites (the http://support.twitter.com, http://business.twitter.com, and more).
Now, we're working on cleaning it up some and prepping it for open source. More to come!
