Evoking the fragility of the natural world, the New York artist Violet Dennison uses delicate sculptural installations to portray the precarious balance between ecology and technology. This online exhibition sees eelgrass collected from Massachusetts mounted on a gallery wall. The pattern is poetic, suggesting a Japanese mountainscape, the wrack line on a beach. On the floor, in the foreground, wood decoys of a goose, a Mallard, suggest an eternal conection that grows ever more abstract. —E.C.
