Summary: Motion picture made in cooperation with the Michigan Foundation for the Arts and the support of the Michigan Council for the Arts. The film documents the sculpture project undertaken by David Barr, an invisible tetrahedron spanning the inside of the Earth with the outer four corners just protruding from the crust of the Earth. The visible corners are located in Easter Island, South Africa, New Guinea, and Greenland. Barr chose the locations as areas untouched by Western technology and in remote areas in order to bridge diverse cultures. Also included is a cassette and transcript of a portion of the sound portion of the film, and a summary of the project by Barr.
