Firefly sync

hundreds of independent flashers nudge every neighbour's clock forward when they fire — synchrony emerges with no conductor.

try push coupling up from zero and watch the random twinkling snap into one pulse — the r in the corner is the synchrony score, 0 for chaos, 1 for lockstep.

integrate-and-fire firefly synchronization: each firefly's phase climbs at its own rate (period ~2s ± 15%); on flashing it nudges neighbours within the radius forward by coupling·(1 − phase) · watch random twinkling converge to unified pulsing · ← more sketches
