Abstract
Abstract A three-dimensional sculpture includes a plurality of members interlocked at their ends to form a polygonal frame. Each of the frame members includes a series of notches formed along their opposing longitudinal edges. A filament such as a string is thereafter passed through the notches on the several frame members to thereby form a highly decorative sculptural pattern enclosed by frame.
