Exhibition 211 was an art exhibition that ran from March to August 2009 in New York City. It was initiated through a series of discussions between Warren Neidich and Mathieu Copelands in 2010 in Paris and New York City. But the series of instruments for its production, like the role of the roll of dice, the picking of cut up names out of a hat and the rules of engagement, see below, came later through discussions between Warren Neidich and Eric Angles. These were further formulated when the program was initiated and programmed by artist friends Elena Bajo, Eric Anglès, Jakob Schillinger, Nathalie Anglès, and Warren Neidich, offering "an experimental and contradictory artistic and curatorial approach", notably a set of rules, defining when, where, and who by, artistic interventions would take place.
