Remanence of a Grassland
Remanence of a Grassland is a speculative sound installation consisting of electromagnetic coils, glass jars, permanent magnets, and control electronics. By pulsing the coils with alternating current, the magnets trapped within the jars may be manipulated in chaotic ways.
The rhythm of the system is the result of a real-time computer program which simulates an artificial group of insects. Over time, the insects within the simulation listen more carefully to their neighbors and adjust the pattern of their songs accordingly. This modification of behavior reflects that of calling insects in the wild [1]. Due to the nature of the algorithm, both small and large groups of insects will fall in and out of synchrony, creating a dynamic sonic landscape that varies widely depending on when it is approached.
