José Carlos Martinat’s work lies in the collision between two diverging notions of public sphere. One, which assumes it as a realm of unrestricted discursive interaction about social and political issues. And another, that takes it as a realm where conflict is institutionalized under the prerogatives of the hegemonic structures of dominance. 
 

By inciting a “misuse” from the spectators, Martinat empowers non-artistic groups as “collaborators” of the work. This inclusion of external factors is re-explored in a number of devices engendered as living, active, transformative and questioning organisms, through which a flow of online information is broadcasted.

His work integrates collections such as: MAC USP - Museu de Arte Contemporânea da Universidade de São Paulo, São Paulo, Brazil; MALBA - Museo de Arte Latinoamericano de Buenos Aires, Buenos Aires, Argentina; MALI - Museo de Arte de Lima, Lima, Peru; MOMA, New York, EUA; TATE, London, UK, among others.
