A moiré that plays itself
A self-playing audio-visual moiré. Tone.js synthesizes four pairs of near-frequency tones that beat; one pair's detune glides so its beat accelerates and settles. A live amplitude analyser drives the blue ring-field, so the visual moiré pulses and sweeps in time with the audible beating. Warm amber rings over a cool indigo field.
