SAN FRANCISCO, CA.- After years of anticipation, Jim Campbell’s Day for Night atop Boston Properties’ Salesforce Tower in downtown San Francisco was finally revealed.

Situated at 1,000 feet above the heart of San Francisco, Day for Night is unprecedented in the realm of permanent public art, not only due to its height and the complexity of its engineering. 11,000 custom-designed, flexible armatures are mounted on perforated aluminum panels surrounding the exterior top six floors of the tower. Unlike a typical digital billboard with glaring LEDs projecting outward, the LEDs embedded at the tips of the armatures shine inward to reflect off the building, creating an atmospheric glow that correlates to San Francisco’s foggy climate.

Even more unprecedented as a public art installation is its integration into the civic fabric and its ever-evolving nature. Day for Night is essentially a visual diary of the surrounding landscape and community, replaying recorded footage, captured by cameras throughout the city, of the ocean, bay, sky, and street life on a nightly basis. The imagery will change every day as a direct reflection of the life of the city and its residents, workers, and visitors. Day for Night raises the bar for the potential for public art and a community’s expectations for engagement.

Not unlike the Eiffel Tower, which was a product and symbol of an era of enormous advances in engineering and technical possibility, Day for Night is a reflection of the power of digital technology and San Francisco’s integral role in that culture and economy. Floating above the night skyline, Day for Night is visible for 20 miles around the Bay Area and is destined to become the new cultural icon for the tech-innovation capital of the world.
