'Acting', the culmination of the exhibition, is embodied in a concrete call to action. 'Acting' presents 5 displays of the mobile devices designed for direct intervention in marginal areas of Italy. They are mobile units mounted on trailers, designed by 5 Italian firms in collaboration with 5 associations long engaged in seeking to curb social and environmental degradation: AIB (Italian Library Association) + Alterstudio Partners, Emergency + Matilde Cassani, Legambiente + ARCò, Libera + Antonio Scarponi / Conceptual Devices, UISP (Italian Union for Sport for All) + NOWA.
