Submerged, Installation, Dinnerware Gallery 1982 Hardesty suspended long PVC tubes at regularly spaced intervals to fill the gallery space. At eye-height, he marked the tubes, wall, and the gallery-front plate glass. Everything from that marking, down was darkened (including the window, covered with tinted sunshield). The effect was perceptual, a convincing state of being in dark water up to your eyes. The effect worked from the street point-of-view as well.
