Black & White Ball Architectural Projection Obscura Digita

The largest black tie fundraiser in the nation, the Black & White Ball is an evening of music, food, and dancing to benefit the San Francisco Symphony.

The event’s organizers invited Obscura to transform the facade of San Francisco’s City Hall into an interactive playground of light and color.

A dozen high-definition projectors and Obscura’s proprietary technology created a stunning backdrop for the 5,000-person, 4-hour party produced by Robert Fountain Design.

A Twitter feed added an interactive element to the spectacle. Partygoers could see their tweets projected on the two-block-long building as well as change the visuals by tweeting special hashtags.
