Django Dash is a 48 hour competition where teams from all over the world build a django based web application. You can see the finished web applications at http://djangodash.com/. All the projects were required to be open sourced and committed to on either github.com or bitbucket.org. The cool thing about that is you can see how all these web applications were build from the ground up and get a feel for how to build really compelling django apps.
The results have now been posted.
I’m sure there’s lots of little tricks for quick development buried in those repos. I know I’ll be digging through them to get some inspiration for future projects.
