Automatic Midnight
A dark background theme with green headers and photographic highlights.
From the site:
I designed Automatic Midnight to be a simple, flowing layout that was very minimal in color while showing nice contrast. It features a nice little tabbed comment system, automatic updates, is xhtml 1.0 Transitional compliant, css 2.0 compliant, and tableless. It’s a little different than most Wordpress themes as it adds some statistics such as post count, comment count, and lists the posts with most comments down the side.
