Fixed-Width / Flexible-Width Hybrid Design

A List Apart, in case you didn't know, is the shizz-nit. A while ago I read Switchy McLayout—an experimental technique to dynamically jump between different layout approaches based on viewport width. A hack, yes, but CSS3's media queries aren't a reality yet.
Since I'm currently using an uncommonly wide fixed-width design, I decided to experiment around with this a little bit. If your viewport width is currently > 960px, and you resize it < 960px, then this page automatically switches to a design fixed at 750px instead of 960px. At least it works on the handful of browsers I tested (i.e. not IE).
