A few months ago, I shared a great-looking combo of themes that give Windows XP and Firefox a dark, unified look. WindowBlinds is an app that achieves the same end, but brings a large gallery of theme options to you. Dress your desktop up or down with default selections or choose specially-formatted third-party themes that download straight into WindowBlinds. Either way, the sharp visuals and full-featured, easy-to-use configuration manager make this application a recommended choice for anyone interested in pimping out their desktop. Aww, yeah.
