Abstract:

This paper presents a temporary multimedia installation set up at the \emph{Civic Aquarium of Milan}. Thanks to four web cameras located in front of the tropical fishpond, fishes are tracked and their movements are used to control a number of music-related parameters in real time. In order to process multiple video streams, the open-source programming language Processing has been employed. Then, the sonification is implemented by a PureData patch. The communication among the parts of the system has been realized through Open Sound Control (OSC) messages.
