Hayes Valley: Patricia's Green (Hayes at Octavia)
A project of the San Francisco Arts Commission and Recreation and Park Department, "SQUARED" is a 50-foot-tall tree “reimagined in a futuristic world post nature,” according to the artist Charles Gadeken. At night, the sculpture performs a light show of in an almost infinite array of color patterns, creating a different experience and ambiance from one minute to the next. Each cube holds 12-24 individually addressable LEDs, programed through custom software to generate millions of colors and thousands of patterns. A pre-set program directs waves of colors and patterns that sweep over the tree to create an ever-shifting kaleidoscope of light. The sculpture also has an interactive mode that can be accessed by a touchscreen to allow visitors to play with the artwork.
Best Viewing: Anytime after dusk.
