Concrete5 theme: Shades of Blue
Shades of Blue is a nice two-column skin, which been originally designed for Wordpress by studiopress.com and converted into concrete5 theme by Smart Web Projects. We like its navigation and the layout in general.
To install concrete5 theme, download the archive (just click on the download button and save zip file to your local machine), then extract it to concrete5 base directory and install it in 'Dashboard' - 'Pages and Themes'. Then you can activate theme to apply it on existing pages.
You can find instructions in README.txt file as well.
