Physarum polycephalum , or slime mold, is an acellular organism extensively studied in scientific experiments and artistic engagements. Artist and critical engineer Sarah Grant collaborates with architect and researcher Selena Savic on hybrid bio-networking experiments with slime mold as an approximation of a computer network. They study communication as an organic process, rethinking networks’ inherent technicity through encounters with a living organism. They discuss network imaginaries situated in the way slime mold forages for food: at once transmitting and materializing its experiences, constrained and conditioned by the environment. The results of this work are imaginative accounts of adaptive network infrastructure and protocols.
