"occupying the main floor of the gallery is a monolithic sunken pyramid that containsa 'vivarium,' an indoor enclosure consisting of a collection of organisms that, in this case, are real, robotic and/or simulated. as a collective, these organisms generate energy capable of transforming a freshwater ecosystem into a brackish one, a process made possible by the permeability controls that the skin of the pyramid produces and the behavior that the 'machine' generates. virtual (digital) organisms mimic the behavior of both the living and 
robotic microorganisms to intensify and ease the process."  via
