The Klenwell theme is a minimalistic green (mint) theme, with a clear bold header and basic two column content layout. In short, you're looking at it.
The stylesheet is adapted from the Wikka Light theme. It takes advantage on the new config directory for both its menus and the feature box at the top of the right-hand column of the home page. Find detailed installation steps below.
