Cablogramma (image above, video below) is a minimalist networked installation of four identical modules each with a microcontroller driving a piezo speaker and three white leds.

The system is designed for autonomously generating simple variations emerging [sic] by a software – based on a cellular automaton – distributed on the four devices. Each modules is a voice capable of simple real time synthesis as well as communicating with other devices (through serial communication). The audio result is an evolving pattern sounding in the between of alarm signals and a micro-spatialized a quattro voci counterpoint.
