Heterogenesis is an interactive sound and tactile environment consisting of a group of autonomous artificial life agents that collectively form a rudimentary artificial neural network. The agents, taking the form of long pillar-like sculptures, generate and evolve a soundscape in response to one another and to the presence of human participants. They respond in three ways: (1) by altering their generated sounds, (2) by communicating with one another so as to “warn” of human presence nearby, and (3) by producing an inaudible acoustic pressure field that “pushes” participants as they approach. Heterogenesis seeks to manifest emergent behavior through the complex interactions of autonomous systems — both human and machine.
