This project follows on from "A wide continuous area of something" released after my return from Australia, fuelled by the continued reading experience (The Expanse by James S. A. Corey).
The Keplerian title relates to the musical approach taken here; it is a bit like 'set something on a low gravity course', but with a defined set of conflicting forces, and let it evolve, slowly. While it changes, influence it; although 'forces' at work here are more like 'aftertouch' and 'modulations' than gravity and thrusters. In that sense, it is less improvised, but still, up to accompany those books and inspired by those.
The picture was not taken under a Ganymede dome but at Bondi Beach.
