Visitors to Light and Space artist Helen Pashgian’s show of new work at Chelsea’s Lehmann Maupin Gallery are invited to sit on benches to appreciate disk-shaped sculptures that appear to hover over pedestals in the gallery, while other pieces require movement to be appreciated. The second scenario applies with this untitled cast epoxy with formed acrylic sphere, which reveals or conceals bands of color as the visitor moves before it. Designed to reveal how perception of a single object or phenomenon can shift, Pashgian’s invites viewers to delight in the nuances of seeing. (On view through Jan 8th).
