27 Gnosis is a destabilizing, combinatorial game show, which premiered in dOCUMENTA (13) and later its theatrical version was restaged at The Kitchen, New York (2012-2013).

Under the instruction of the Rigid Designator (Michael Portnoy) and Modifa—the Modifier (Kira Nova), a limited group of players compete to develop a series of confounding propositions formed through the interplay of a set of 27 "gnoses," sculptural forms each representing a heuristic or conceptual tool for attaining experiential knowledge. The language system of the game borrows structurally from the ontologies of 17th Century taxonomic languages as well as elements of modern constructed languages such as Ithkuil, aUi, and Ygede.
