On particularly gusty days in Pittsburgh, the exterior of the Pittsburgh Children’s Museum becomes alive with undulating ripples.

The museum’s watery-wave installation, that environmental artist and sculptor Ned Kahn calls “Articulated Cloud,” is a made of thousands of plastic squares that flutter in the wind. Kahn uses different moveable materials, from plastic to aluminum panels, to make wind visible. The 2004 Articulated Cloud in Pittsburgh is one of several of Kahn’s futuristic and wind-inspired architecture artworks seen around the world.

Wind Veil

In 2000, Kahn transformed this parking garage in Charlotte, North Carolina to make it look like it’s covered in silver, gauzy linen. The 260-foot-long and six-story tall structure is covered with 80,000 hinged aluminum panels that reflect and filter light. Whether a gentle breeze or whipping wind, the façade of the gleaming building turns into a metallic field of waving grass.

Wind Arbor

Half a million aluminum panels swing on this 6,800-square-meter cable net structure that covers the glass panels of the Marina Bay Sands hotel in Singapore. At the beginning of the clip, you get a close-up look at the individual materials bobbing in the breeze. The “Wind Arbor” is not only beautiful, but it also serves to block out heat and sunlight from the lobby.
