I had the loose idea to use different textures to correspond to the rings of Saturn and travel from outside inward, with more rings coming into view as more and more textures swirl around at once, reaching the planet in the end. I think ultimately this is analogous to how one might construct a song anyway, but it inspired me to focus on building lots of little machines to generate textures and rhythms all their own, forming a modular-like atmosphere of semi-happenstance (or let's say "controlled happenstance").
