Phyllotaxis spirals (derived from the golden angle) make such an elegant coordinate space for radial audio visualization because they avoid the density distortion of concentric circular rings.
The trickiest part in these builds is usually balancing transient response with temporal smoothing so the LEDs don't devolve into jittery noise during busy frequency passages. Curious if you're doing per-bin decay filters on the FFT or handling dynamic gain normalization upstream?
