Mariotti proposed Castrillon a different idea: to develop open the game by calling artists and cross-cutting creative agents in a sort of festival, which challenged all categories and hierarchies.
Mariotti and María Luy, his partner, were absorbed by the promises of a revolution Andean, and moved in September 1972 to Cusco and Puno, where they develop art and communication projects in popular sectors, which includes the socialization of serigraphic techniques among the peasant population.
[6] In the late 1970s, after the military junta was over, he returned to Lima and started Huayco E.P.S (the acronym for "Aesthetics of Social Projection"), created as a creative cooperative studio.
[9] His works are in collections of major museums and private collections, such as the ZKM Museum für Neue Kunst, Karlsruhe, Germany; Kunstmuseum Celle mit Sammlung Robert Simon, Germany; MALI Lima, Perú; Museo de Bellas Artes, Caracas, Venezuela; Kunsthaus Zürich; Video Library Sammlung Julius Bär, Switzerland; UBS, Locarno, Switzerland.
[8] In 2018 as a part of series of events organized worldwide to celebrate the 50 years of the Leonardo journal, a local tribute to Mariotti was given by Alta Tecnología Andina - ATA, the National School of Fine Arts in Lima and Proyecto Amil to mark the 50th anniversary of the "Projekt Geldmacher-Mariotti 1968" during the documenta4 in Kassel.
