zBench

zBench has a really polished design that can give your blog a more technical look—without appearing too cold.

zBench has a lot of great features that make personalizing your blog a snap. Features like custom background images and colors, a custom header image, bonus widget areas in your site footer, and custom menus with beautiful drop-down effects. One of our favorite features is probably the alternate layouts available in Appearance → Theme Options. With one-click you can have your site sporting multiple sidebars in several different configurations!
