Author of numerous performances, printed projects, and self-organized events in the 1980s up to the mid-1990s, Gygi has always claimed a social and political dimension to his work. The architectural structures or the public systems that he reproduces (screens, terraces, tents, stands, etc.) reveal the authoritative aspects and the control systems of our society. The publication brings together all elements of the artist's production, and is accompanied by several essays.
