Autopoiesis is an audiovisual projection work simulating biomass bloom in optimal conditions, where a vigorous and overwhelming experience is created through glowing patterns and ambient biological noise in the space. This experience refers to algal bloom that is seen as an environmental hazard as well as a biofuel factory. As the most ancient organism, cyanobacteria make up most algal blooms while assimilating atmospheric  carbon dioxide and producing the largest amount of oxygen on the earth. With multi-layered soundtrack composed of individual faint sound pieces produced by cyanobacteria’s oxygen-containing bubbles, this invisible and under-heard behavior is augmented by computation with the abstract reproduction bringing the question of the essential substance human relied on and their circulation in the earth system.
