Interferences of theMultitude is an introductory analysis of the perspectives collected under the umbrella of the homonymous track, presented during the Rogue Research edition of the 3rd Politics of the Machines Conference in Berlin (September 14-17, 2021). The paper examines the implementation of arts-based research into the new modes of techno-ecofeminist imaginaries and investigates its generative potential for the enactment of the new materialist and feminist ethics of care, collaboration, and solidarity. The projects presented and discussed span the entangled fields of human-computer interaction, computer-supported cooperative work, material sciences, critical design and making, architecture, machine learning, interactive art, and post-human performance.
