Last March I blogged about SF’s plans to turn the Bay Bridge into a giant, public LED art installation, with help from renowned LED artist Leo Villareal. (Incidentally, Villareal also graced this blog in 2010 when I wrote about the beautiful dimmable LED pieces he displayed at the San Jose Museum of Art.) The full unveil of the LED strip light-adorned Bay Bridge will come in March of 2013, but today, a video of many of the 25,000 DMX LED lights being tested came out, and it proves the renovations will be well worth the wait. All along the massive struts and bracings, cascading LED lights will drop in sequential patterns that illuminate the stunning architecture of the bridge and lead the eye all along its length. Once programmed, the LED lights will illuminate in patterns that reflect the current traffic, weather and wind conditions in the surrounding area. And, remember, this project isn’t just about aesthetics. It’s also helped out the local economy by creating hundreds of jobs and adding an estimated $97 million to SF’s revenue stream. Big numbers for a big concept: when complete, “Bay Lights” will be seven times larger than the Eiffel Tower’s 100th anniversary lighting installation.
