“Singularity” (2013)
This one needs to be listened to. Ignacio Pecino specializes in procedurally generative audio: the sounds in this video are being generated in real-time from the cellular automata that he refers to as automata sonification.
The video has an overarching linear structure, defined by the particular patterns it starts with, but the moment-to-moment result is generated. In my terminology, it uses a closed progression system to give the video order, and an open, generative process to introduce meaningful chaos.
He has an online demo of audio generation with Conway’s Game of Life that yoiu can play around with: http://ignaciopecino.com/automata.html (Uses Unity, so Firefox works better than Chrome.)
