Hidden Sea by Ned Kahn 2000

Recipient Organization: Tenants and Owners Development Corporation

In late 1999, artist Ned Kahn collaborated with the staff of the Tenants and Owners Development Corporation (TODCO) and the residents of their housing projects to create a public artwork for the exterior wall of Ceatrice Polite apartment building at Fourth and Clementina Streets. The apartment is in the Yerba Buena redevelopment area.

Ned Kahn’s public artworks encourage people to observe and interact with natural processes. Upon talking with the advisory group, his concept for this project became to create a piece that captures the feeling of watching a field of tall grass blowing in the wind. Both Kahn and John Elberling, Executive Vice President of TODCO, felt that the residents would benefit from being offered a glimpse into a natural phenomenon, a bit of calm and beauty in the context of their increasingly dense and bustling urban landscape.

The artwork, “Hidden Sea” consists of 6,000 small aluminum “leaves” mounted in an aluminum framework and hinged to move freely in the wind. The individual leaves measure three inches by three inches and are held by low friction bearings. The entire 40-foot tall by 25-foot wide artwork reveals the shape of the wind and creates the intended impression of waves in a field of metallic grass. The mirror-like surfaces of the aluminum leaves reflect light from different parts of the sky and the surrounding buildings.

“Hidden Sea” was fabricated by Ace Precision Machine in Santa Rosa and assembled in Ned Kahn’s studio. Benji Young and Michael Ehrlich of Young Rigging in San Francisco installed the artwork at the beginning of the year 2000.

Ned Kahn writes of the context for this project:

For the last 15 years, I have created public artworks that use wind, water, fog and other natural processes as their primary medium. Many of these artworks were intended to reveal a hidden or unnoticed force in the site such as the air currents or the ambient light from the sky. The design of a number of these projects was based on an aspect of the natural history or geology of the region that was not commonly known. My artworks often function as small-scale “observatories” in that they frame and enhance our perception of natural phenomena and create places that encourage contemplation.
