The “Air Wave” installation was commissioned by The Architectural League of New York to respond to the theme of “threshold.” Rather than see a threshold as a physical transition, “Air Wave” defined it as the magnitude or intensity that must be exceeded to initiate a particular physical reaction. A threshold is a limit. It can be a physical limit as well as an invisible boundary—like the liminal yet invisible boundaries of sound and air movement. Installed in the vast hall of a former manufacturing facility, the project was suspended in the air and appeared above visitors as an upside-down landscape. The fabric surface was put into constant movement by an array of suspended fans.
