Thanks to Michael Heilemann's detailed tutorial and some spring cleaning of my desktop files (half an hour ago, there were about 300 files on my desktop, now all organized into directories), my workstation PC looks like this (with windows up, everything minimized -- both ~200kb jpegs), and I'm extremely pleased with the look and improved workflow. I share my desk with a powerbook I customized to behave more like windows, and now I can get both desktops to behave almost exactly the same.
