Yeah, treat the moon as a periodic trigger, map each phase to a state in a finite‑state machine, then output a different chord progression each cycle. Add a little noise or a small random offset so it never feels completely deterministic. That way the code has a living rhythm, like a living loop that wakes up whenever the new moon hits. If you want to make it truly alive, feed the program some real‑time sensor data from a lunar calendar API and let it adapt. And hey, if you forget lunch again, just think of it as optional firmware maintenance.
