Gespaa is a single column blue gray theme.

From the site:

Gespaa is an attractive, smart theme that was originally designed for private use on this very blog.

An elegant and subtle theme based on the Photanical theme by Theron Parlin. Has a static header and a primary link bar.

From the site:

It’s a black theme for minimalists.

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.
