Salesforce Tower – San Francisco

Restoration & Maintenance of “Day for Night” by Jim Campbell

Day for Night is an iconic large-scale public artwork by artist Jim Campbell, located on the top eight floors of San Francisco’s Salesforce Tower. The installation features over 11,000 custom-programmed LEDs, which display atmospheric, low-resolution video imagery across the building’s facade—making it one of the most visible digital art pieces in the city skyline.
