Turn Audio on and allow the mic. Tap Start — this phone listens like Neighbourhood Chord (chroma from the room) and entrains rhythm like Firefly (mic pulses from neighbours).
A layered drone choir slides toward the group key; sparse clicks and pings keep it alive. Every few bars a small genetic algorithm breeds new voicing and patterns that fit what it hears.
Play in a circle at moderate volume. Each phone evolves differently — together they form a shifting harmonized texture.
Evolve now forces a new generation. Visual pulse flashes on rhythmic hits.
