A 260’ long by 6-story tall facade of a new parking garage in Charlotte, North Carolina was covered with 80,000 small aluminum panels that are hinged to move freely in the wind. Viewed from the outside, the entire wall of the building appears to move in the wind and creates the impression of waves in a field of metallic grass. Inside the building, intricate patterns of light and shadow, similar to the way light filters through the leaves of trees, are projected onto the walls and floor as sunlight passes through this kinetic membrane. In addition to revealing the ever-changing patterns of the invisible wind, the artwork was designed to provide ventilation and shade for the interior of the parking garage. Commissioned by Bank of America. Completed in August, 2000.
