The Len Lye retrospective at the Wellington City Gallery showcases three areas of this New Zealander’s prodigious output: photograms, animated films, and kinetic sculptures. All the works on view reflect a sharp mind at work, but it’s the sculptures that really shine as the simplest of mechanical actions are shaped into an endlessly entrancing counterpoint of movement and sound. A large steel loop bobs gracefully and occasionally strikes a wooden ball hanging above it, a stately collection of arcing metal rods pivot and turn erratically, and a verticle blade shudders intermittently to life. Built in the 60’s and 70’s these pieces seem as fresh as ever and more than hold their own against most the tech art produced since then. Through November 24.
