I'm glad to see so many Arch Linux related wallpapers, etc.. on kde-look. For those that don't know, Arch is a fantastic Linux distribution that is based on the 'Rolling Release' model. That means there are no Arch Linux 'releases' like 10.2, 10.3, etc.. Each time you do an update in Arch, you are updating to the latest version of Arch. It doesn't come with training wheel, but has a good installer and great wiki. If you can read, you can successfully install Arch :p
