Responsive Grid Framework written in Stylus for Node.js

I've been hooked on Node.js for the last 2-3 months. I've been doing some small projects for fun in Express, and at first I used the SASS complier that ships with Express by default. That framework is pretty limited and TJ Holowaychuk pointed me towards Stylus, a much better sass complier for Node.js. I tweeted something about Stylus a couple of days ago which resulted in a fellow countryman, named Jokull Solberg (www.solberg.is), showing me a responsive grid framework he made in Stylus. So far it's only a gist on github, but feel free to check it out: https://gist.github.com/1501983 So far it supports four screen sizes, but it's easy to extend.
