Instant city is an interactive music-building game by Swiss artists Sibylle Hauert and Daniel Reichmuth.

Participants - or players - are invited to create architectural compositions using semi-transparent building blocks and in the process make different modular compositions audible. What can be heard thus depends directly on how high the structures is and, many blocks are used and in which order.

Instant City neither has a winner or loser nor an ending - instead it is shaped as an endless collaborate social space.
