Wind is an invisible element. By creating a wind-driven kinetic facade on the the blank wall of the Randal Museum in San Francisco, Charles Sowers Studios sought to give it shape and form. Windswept is a scientific observational instrument that consists of 612 freely-rotating directional arrows. Each arrow acts as a discrete data point, visually revealing the complex and ever-changing ways the wind interacts with the building and its surrounding environment. The design studio spent over a year and a half designing and testing wind arrow designs, which are made of brake-formed anodized aluminum. The installation itself is 20′ high x 35′ long.
