Party Wall, an interactive installation unveiled at Artists Space ( 38 Greene Street, NYC), on March 9th, creates a variable boundary in the gallery, dividing visitors into different sides of a room. Party Wall allows "neighbors" to dynamically modulate the thermal, acoustic and spatial qualities of a simple screen made with 2" thick bands of foam. In this initial prototype, proximity sensors embedded in the foam detect the presence of "neighbors" and trigger tiny servo motors. The motors exert tension on synchromesh pulley cables attached to the foam layers, causing variable compression and expansion, and resulting in varying apertures and densities of foam. Beyond raising issues of property and ownership in the gallery context, future iterations of Party Wall could respond to light, heat or sound, and correspondingly modulate optical, thermal or acoustic attributes of a wall.
