Two hundred voices, each singing alone, slowly finding each other.
Each particle is an oscillator with its own natural rhythm. When near other particles, their phases pull toward alignment — a model called Kuramoto coupling. Isolated particles flicker independently; clusters begin to breathe together; eventually the whole field synchronizes into a single pulse. The sync meter shows how coherent they are. Lines connect particles that are in phase.
