A large collection of small oscillators has a desire to synchronize. Just like fireflies, the cells in your heart, or perhaps ideologies online, they work on the principle of pulse-coupled oscillation. Their pings are heard over a mesh network, and as each oscillator is influenced by its neighbors, they gradually coalesce into groups. The process produces a cascade of rhythms.
But this system (like all systems) is not closed. Visitors disrupt or encourage the relationships by moving the oscillators around, and their movement forms a complementary human choreography.
