In Dunkirk, Millimètre studio designed a game for children (and grown-ups too!). White 3D-printed blocks can be put together to build cityscapes, while colored tiles embody different kind of grounds, as seen from aerial photography. The cities can be built on a 25 m² board, allowing different cities at the same time.
For this game, I designed a real time soundscapes device that reacts to the size of the cities built on the board. The bigger the city, the more urban and harsh the soundscape. And the smaller the city, the more natural and quiet the soundscape. 8 soundscapes are generated in real time and each broadcast in a different area of the board game. An article (in French) here.
And an excerpt below:
The soundscapes are broadcast through audio exciter, making the sound very immersive and as if it were coming out of the built cities.
The real time soundscapes generation is run by a Max/MSP patch, which uses data from a PixyCam camera and an Arduino.
