I ran across an interesting project for christian filmmakers a little while back. The project was to make a three minute long video in 36 hours from the project start date. Each film had to contain three elements from a list in the project rules so they you could prove that the film wasn't made before the start of the project. You can check out their web sight here and watch the videos through youtube. And I've posted some of the videos I liked best if you care to watch them.
