Certain exemplary embodiments can provide and/or utilize a system comprising a first sheet formed of a light-diffusing material, said first sheet defining a pair of opposing faces and two pairs of opposing edges, said first sheet adapted to provide a substantially uniform illumination from at least one of said faces when light is transmitted into any of said edges; a first reflective layer adapted to reflect light toward a second face of said pair of faces; a second sheet formed of a light diffusing material; and a first light source adapted to transmit light into a first edge of said edges.
