Flow Eden

A living sonic ecology. A finite budget of matter flows across the grid under a mass-conserving Flow-Lenia rule; three species compete for it, spread, collide and drift. Sound and image are two views of one simulation — the music at minute five is genuinely different from second five, because the population has evolved.

Each species is one voice, pitch-quantized to a shared D pentatonic so the whole is harmony. Population mass sets a voice's presence; a species' center of mass pans and bends it; blooms, takeovers and near-extinctions ring bells. Click Start, then just watch and listen — it runs and evolves on its own. Tapping the field drops a fresh blob.
