A "self-organizing evolutionary musical organism", that's how the makers of Bacterial Orchestra define this sound installation. The cells in this organism are made of speakers and microphones, listening to the sounds that are surrounding them.
Visitors interact with Bacterial Orchestra by simply making a sound. I like the idea of having a system that takes your input and gives it back in a new form. The installation is created by Olle Cornéer and Martin Lübcke.
