Roger Johansson takes a step further the debate that wouldn't die between proponents of fluid and fixed web designs. His in-between approach is demonstrated by his own recent "elastic" redesign. Resize the font on his site to see it in action. Look at the masthead and main column width -- nice! Elastic is liquid done properly to make sure things don't expand into silliness in higher resolutions, while acknowledging that the user is in control.

Nice to have for content sites, but even nicer for web apps. The severely constrained layout of Movable Type's backend for instance makes me cringe and would no doubt benefit from this.
