The Amsterdam Foundation for Arts organised PROTOPARK in the Siegerpark in Amsterdam. PROTOPARK was about creative experiments with the public green domain.

Beneath the surface of a pond 4 synchronous airbubbles float up to the water’s surface with intervals of 10 seconds.
This is a reference to the gaseous and fen-like subsoil in Amsterdam.
The expanding circles on the water’s surface touch each other and will create a geometric interference pattern.
