About the Artwork:
The sculpture consists of four intersecting cones and functions as a solar calendar or sundial. The angled flat surfaces interact with the sun throughout the year, with the forward side in full light in the winter and the back surfaces filled with the summer sun. It is part of San Francisco's 1% for Art Program
