Artist Leo Villareal created “The Bay Lights,” a public art light sculpture across the San Francisco Bay Bridge, which will shine for two years starting March 5, 2013. The artwork is made up of some 25,000 energy-efficient LEDs, mounted on vertical cables 30 feet apart. The LEDs are controlled individually by computer, with the light turning on or off some 60 times a second via a 1.8 mile fiber-optic cable, to create a variety of patterns that flow into one another. He states, “I’m interpreting all the kinetic activity around the bridge: the traffic, the motion of water, the sky — it’s such a rich environment to draw upon.” The artist told a reporter at Mashable that the computers controlling this are a “bunch of $500 Mac minis mounted inside the bridge” and that those Macs are running Windows via Apple’s Bootcamp. Wow!
