Last week, Adam Kaplan released Grid, deeming it “A simple guide to responsive design.” I’ve been playing with the Grid system for the last few days and it’s fantastic. If you build, or are interested in building websites, you really need to check this out. Great work.

UPDATE: the Grid website seems to be experiencing problems. If you can get through then great, but if you can't then you can check Grid out in a less pretty format where Kaplan is hosting it over at GitHub.
