Microbial Cosmologies imagines a Future of Mobility that is entirely built around the most successful type of organism on the planet—the microbe. Employing speculative design, industrial design, mechanical engineering, AR, VR, and Machine Learning, we created a world in which humans redefine our relationship with microbiome to make space for inclusive human/nonhuman assemblages and develop methods for designing for, with and around the microbial world within and around us.
