Not only are these cameras sculpture but they work in some interesting ways.

The Wood Camera is made from Wood, Aluminum, Copper, Steel, Acrylic, and Insects. Most of the camera parts were found in Death Valley, CA. The camera has an interchangeable front plate used to float objects in front of the pinhole. With pinhole photography the focus is infinite. Objects which are a quarter-inch in front of the pinhole are just as in focus as objects 20 miles away.
