big fans of Debian here ... two of us from the LE team (designer + UX/UI guy) made the following preliminary designs. we have more ideas, but as with any design project we want to make sure the path is on target, before spending more time creating additional screens.
our goal here was to think from the user perspective and go with a nice, clean minimalist - but still good looking and high-end design.
connect with us or me (Dmitry) at http://www.localelement.com - comments and ideas are appreciated. we are very happy to help grow Debian!
