Permanent installation in 6 glass panels forming a wall: 16.87 m (60 ft) wide, 5.40 m (16 ft) high, 0.50 m (20 in) thick. Each section is 2.81 m (10 ft) wide and 1.27 m (4 ft) high.

Clouds of feathers captured in a large glass box evoke the presence of air. Made of three layers of feathers, the clouds vary in their density and transparency, shaping the transmission of light through the wall.
