Eugene reminds us about the KPresenter template contest. This made me go "hunh? did I miss something?" and yes indeed, there was an announcement on the dot some time ago.

Of course, my artistic skills are limited to Kolourpaint and LaTeX beamer hackery, so I'm not going to enter, but I'd encourage all those with actual talent to submit something. Spice up everyone's presentations! Do bear in mind that the license on the resulting artwork needs to be liberal enough that it can be redistributed -- consult the contest rules for details.
