SAN FRANCISCO (KRON) -- A public art installation in San Francisco’s Civic Center made up of 1,271 LED lights and spanning more than an acre of space above Fulton Plaza is set to make its debut on Saturday night. The art installation, named Spectra, “will pulse and shimmer in an audio-reactive display of color and light,” nonprofit Illuminate and the San Francisco Recreation and Park Department said in a news release. “Arranged in a dynamic waveform that mimics both light and sound spectrums, SPECTRA ripples across the sky.” Spectra public art installation at Fulton Plaza in San Francisco's Civic Center.

Public art belongs to everyone—it’s a living, breathing entity, and SPECTRA is a reflection of the energy we all bring to it. It's more than just light and sound, it reflects the vibrant and diverse spectrum of individuals who shape this city and call it home.” SF renames skatepark in memory of blind skateboarder who passed in 2023 Spectra will come to life around 8:10 p.m. on Saturday, April 5, and continue to be exhibited seven days a week, park officials said. The debut falls on SF’s “Night of Ideas,” which is described as a free event celebrating art, culture and innovation in the city. ...read more read less
