Computer programs allow interaction, hence they distinguish computer art in a way prints can't. Philip George's layered images are among the most compelling computer art, and they were here tastefully animated by Ralph Wayment's programming. Also intriguing was Youn Lee's, "The Land of Time."

Most successful in a gallery setting were the computer sculptures. Chuck Genco's "Eye Box," was notable. From inside a beautifully crafted wood and brass box a glass eye randomly blinked its mechanical eyelid. On the inside of the cover: Ptolemy's map of the solar system. The eye perhaps contemplated progress toward a helio-centric view.

More ambitious was Peter Terezakis' "Rubaiyat." This grid of patinated electrical boxes and conduit was intended to vary the multi-layered sound it generated in response to viewer movement. It was hard to discern the tonal changes produced by any particular motion, but the fact that one wanted to experience the interaction suggests the potential power of digital sculptures.
