Box for Expression is an attempt to co-create a ‘common space’ within the urban/rural public space. Physically, it is a modular, reusable and re-adaptable open infrastructure. It offers the possibility for users to add oral stories into the cloud, gradually forming a collective narrative of passengers. It aims to create an open-source and accessible infrastructure, focusing on the idea of the "commoning" at the intersection of digital civics, fabrication, social research and artistic practice
