Valkaama is a feature-length collaborative, Open Source movie. It means, among other things, that the source materials are available for (re)use and (re)mix. A fine example of this is the music of the movie, or actually three different versions of it.
Valkaama is from Finnish words "valkama" (home) and "kaamos" (polar night)
The movie has (as of May 2010) 3 different soundtrack versions.
