An overhead media display system for installation of signs and display elements on a suspended ceiling and other ceiling fixtures is disclosed. The present system includes a plurality of interchangeable display structures of different geometric shapes and sizes, which are constructed from both transparent and translucent materials that function with backlighting being installed directly underneath ceiling light fixtures and, alternatively, from opaque plastic materials being attached at ceiling locations without direct illumination. Each sign or display element includes integral retaining flanges with compressive elements that are formed by the use of die-cutting, scoring, folding, and other assembly techniques during construction thereby eliminating the need for fastening hardware and adhesive materials for installation. Each sign or display element is fabricated from a single blank of material, which is imprinted, die-cut, scored, folded and assembled to provide optimal structural strength to function as a permanent store display for presentation of product advertising and commercial art, but is sufficiently versatile and inexpensive to be used for temporary sales promotions. Motion and enhanced visual interest may be imparted to the present sign system by the addition of interactive sign elements rotatably mounted on the interior and exterior of the signs. Rotational movement of the interactive sign elements is provided by a miniature electric motor powered by a photovoltaic cell array, which generates electrical voltage derived from the adjacent light fixtures.
