one-aftr was formed with the mission to create a 'collective good experience' in space. We use the vagueness of 'good' as a driving force of our inquiries. We make sense of what surrounds us through measured observation of everyday life and through the viewpoint of other fields. We experiment with ways of working in defining the 'good' through writing, making, curating, and building.
