Salesforce Tower, the new skyscraper dominating San Francisco's skyline, lit up for the first time in April. That first show was just a test, but now, every night starting at dusk, silhouettes of dancers and other images move against a bright background across the façade of the top six floors of the 62-story building. The show is called "Day for Night," and it goes on until 2 a.m.
