Simplicity.. That is the easiest way to describe the Carbon theme for the Nokia N900, elegant yet straightforward.
The Carbon theme is definitely one to have. It adds a touch of class to the home screen, and its custom icons for the application manager and other menus makes the theme well worth it.
Not many details are available for this theme, but it can be downloaded from the Maemo Repositories.
