From gossamer dryer sheets to metal refuse rescued from local rivers, cast-off objects that imbue the spirit of reuse and recreate give shape to a dynamic exhibit that runs through Feb. 25 at Columbia Center for the Arts.

“Back Talk: Recycled Art” features jewelry, photography, small and large metal sculpture, mosaics, and drawings, all made using materials that had once been something else: cast-off pencils, old shovels, glass shards, building materials, bottle caps, paint sticks, plywood, and more.
