The Golden Gate Bridge is getting a little sparkle for its 75th birthday.

Starting Sunday, remotely operated mirrors on top of the bridge’s iconic towers will flash narrow beams of reflected sunlight all around the San Francisco Bay in an installation that marries art and science.

“We love our view of the bridge. We’ve always wanted to enhance it with a little sparkle,” said astrophysicist John Vallerga, whose offices at UC Berkeley’s Space Sciences Laboratory in the Berkeley Hills overlook the bay.

After the project’s Sunday debut, members of the public can arrange their own brief performance by going online to the installation’s website and entering a fixed location and time when they would like the mirrors to point the beam in their direction.

Part of the bridge’s yearlong birthday celebration, the project, called Solar Beacon, will remain in place until Aug. 30.

Bridge workers on Friday installed one of two sets of mirrors, or heliostats, atop each of the bridge's two 746-foot towers. The heliostats, about two feet across, are swiveled and tilted by motors directed by cellphone commands.

“It’s art in progress. It’s never been done before and we don’t know what it’s going to look like,” said Vallerga, who is executing the project with a group of volunteers.
