It seems like this is an area that is completely lacking. I've been looking for a django project, perhaps a meta-django project is a good way to go ;).
Maybe if designers could upload a set of templates against a simple and well defined set of models. They could upload a "main.html", "object_list.html", "object_detail.html", a css file and a few images. This would be something akin to the CSS Zen Garden project.
I've setup a github repository here: http://github.com/JudoWill/DjangoTemplateRepository. Feel free to log into the project and modify the wiki with requests.
The idea being to give newbies a starting point and a few examples for making their django website.
