    In case it's of any interest, the circuit has its roots in this phase-shift oscillator: https://en.wikipedia.org/wiki/Phase-shift_oscillator That has three RC networks and just a single transistor to give…

    Although this is a digital solution using a MAX7219 chip, it shows a fun application of LED diffusion around 6:40 www.youtube.com/watch -Sean
