Piano Bloom
Play your piano into a living reaction-diffusion field. Touch grows blooms; the reader probes granulate and re-voice the recording back at you.
An instrument you play
A Gray-Scott reaction-diffusion field is the resonating body. Press Begin and it blooms with sound immediately — a warm felt-piano bed. Then touch to sculpt the field, drag the glowing reader probes over it, and (optionally) drop your own piano recording to be granulated and re-voiced.
