Locidesktop was my coffee shop coding project of last year. I was quite pleased with the results. Locidesktop.com has been happily serving link desktops to some loyal visitors for months now – with no maintenance required on my part (a good thing because I've been busy with other projects).
There's also a pretty powerful caching system that makes rendering a desktop blindingly fast. I may have gone overboard with that, given my traffic rates. But I guess it is best to have more capacity than you need.
If you want to look through the code or fork the project, it is available on Github:
The only thing missing from the open source version is a single-site theme I purchased from themeforest.net, used in a few pages such as the about & privacy urls. The desktops themselves are identical to the live site because I did those myself. You can tell because of the minimalist design reflecting my artistic abilities (minimal).
There's a README in the project that will help you get started, but other than that you may have to figure things out for yourself. It's a pretty standard Django project, although I do use Jinja templates rather than Django templates. If you have any questions, please ask them in the comments, so at least there is a central repository for issues.
For more information on Locidesktop, see my previous posts on the subject.
Update: I had to recreate the repos to remove a bunch of temp files and mercurial data. If you forked before 9am GMT, 10th Jan, you may want to get this new repos.
