Installation artist Bruce Munro has added to his fiber-optic Field of Light in Paso Robles. Nestled into a hillside at the edge of the 15-acre site are 69 Light Towers, each made of 252 wine bottles (in homage to local vineyards), with filaments that turn the luminescent forms into colorfully mutable jewels. 4380 Highway 46 East, Paso Robles, 805-226-4287, sensoriopaso.com.
