In the summer of 1975, Bob Miller (1935–2007) started sharing his discoveries about images and sunlight with friends in a series of demonstrations known as Image Walk—then, later, as Light Walk. At the time, Bob was an artist building his now-iconic sun, prismatic, and reflection exhibits for the Exploratorium.
Bob’s Light Walks blended performance art and experimental, hands-on teaching. These demonstrations have been continually nourished by the observations, questions, and astonishment of visitors, teachers, and staff.
In January 2015, we took a guided journey outside the museum with a single image of the sun and ended the journey inside with exhibits on images and shadows.
This program was in conjunction with the exhibition Light Walk: Bob Miller and the Exploratorium, which was on view at the main branch of the San Francisco Public Library through February 5, 2015.
