Coming of age as Spain walked into the abyss of the economic crisis, we describe how we re-functioned our ethnographic project into a ‘prototype’. We borrow the notion of prototype from free culture activism: a socio-technical design characterised by the openness of its underlying technical and structural sources, including for example access to its code, its technical and design specifications, and documentary and archival registries. These ethnographic prototypes functioned as boundary objects and zones of infrastructural enablement that allowed us to argue with our collaborators about the city at the same time as we argued through the city. Providing a symmetrical counterpoint to the actions of free culture hackers elsewhere in the city, our anthropological prototypes were both a cultural signature of the radical praxis taking place in Madrid today and its expressive infrastructure.engAttribution 4.0 Internationaljournal article1469-588Xrestricted accessCollaborationPrototypesEthnographyFree cultureMadridInfrastructureCiencias Sociales63 Sociología
