How about releasing the source without any of the art assets or interface nibs? Full benefit of open source while still providing high value for money. (Sure, the geeks will go and create their own assets, but it won't be the same.)

Interesting idea, but I suspect that the first quality fork that provides a 'good-enough' version of those missing assets out of the box would start to steal the limelight from the main project, especially because the fork could pull in all the bug fixes and new features from upstream.
