Open Source 2.0 (TV series)

This is a unique production project where participants work together, although not at the same time, to build a new work of media art. The project began with a single piece of video, which the next contributor was able to add to, take away from, or alter in any way they chose so long as their contribution was clearly derived from the work leading up to it. The next contributor added to or took away from that work, and so on. - IMDb
