Open the pond, press Listen, then throw in some peas. The ducks gather, wander and call from different positions around you.

The Duck Pond, by celphase, makes its duck sounds with a live synthesizer rather than replaying recordings. The creator used Claude to help build the project and tune its vocal models against reference recordings, including comparing spectrograms. AI helped make the instrument; the running pond produces its calls procedurally.

It is a small, unhurried sound toy. Headphones make the spatial layout easier to notice; the pea button gives you something to do while you listen.
