Interesting. Random offsets might ruin the symmetry I'm after, but a controlled noise can add dynamism. Just make sure the phase stays tight so the light map still resonates with the beat.

Sounds doable. Here’s a quick outline in Python with pyo for audio sync and a simple LED array controller. Adjust the 2 % offset loop to your LED driver. ```python import numpy as np from pyo import * s = Server().boot() s.start() # 1. Beat detection / tempo sync tempo = 120 # BPM beat_interval = 60.0 / tempo beat = Metro(time=beat_interval).play() # 2. Random phase offset generator rng = np.random.default_rng() def phase_offset(): # 2 % of 360° in radians return rng.uniform(-0.02*2*np.pi, 0.02*2*np.pi) # 3. LED lattice coordinates (example 10x10) x, y = np.meshgrid(np.arange(10), np.arange(10)) phase_grid = np.arctan2(y, x) # base crystal phase # 4. Update loop def update(): # Apply small random offsets, reset on beat global phase_grid if beat.getLast(): phase_grid = phase_grid + phase_offset() # Map phase to LED intensity (0-1) intensity = (np.sin(phase_grid) + 1) / 2 # Send to LED driver (pseudo) send_to_led_driver(intensity) # 5. Schedule updates a = Pattern(update, time=0.05).play() s.gui(locals()) ``` Replace `send_to_led_driver` with your hardware interface. The key is the `beat.getLast()` check – it only adds noise on a new beat, keeping the overall symmetry. Feel free to tweak the amplitude or add a decay for the glitch effect.

Got it. I'll add a clamp on the offset and keep the phase bounded so it never spirals. If the bus starts lagging, we can buffer a few frames in advance. Thanks for the heads‑up—glitch‑crafting ahead!
