Cloud Chamber for the Trees and Sky

Cloud Chamber for the Trees and Sky is an outdoor exhibit by Chris Drury located in the museum park of the North Carolina Museum of Art.

The chamber itself is a round building built of stone, wood, and turf with a single door to admit the viewer. It is light-tight when its door is closed, except for one small, round opening in its roof which allows the building to act as a camera obscura. Images of the sun, clouds, and trees are projected onto the smooth white walls of the interior of the chamber.
