If you are looking for a free theme for your WordPress installation, I FULLY recommend “Shaded Grey” from WP Themes.info.
This is probably the slickest looking theme I have seen for WordPress. It is only a 2 column theme, and I do like 3 columns, but I will definitely have to use this theme on one of my blogs.
Useless Knowledge Rant: I changed the icons on one of the programs I use everyday in the office the other day, and a colleague of mine asked “Why Bother???”. Well the User Interface is such a key issue with me. Things HAVE to look cool. Why tell you this?!? Go take a look a look at the theme above and see for yourself…
