Hackcamp is a model of encounter with a very concrete methodological purpose: to bring together a group of people with different knowledge and skill sets for at least two and a half days to respond to challenges faced by a community or institution. The result is always a prototype that partially meets the posed challenge. This model of meeting facilitates creativity and collective intelligence, relying on visual, performative and non-verbal tools to foster meaningful knowledge exchange between persons coming from different social spaces and backgrounds.
