Abstract: A panel comprising a substrate having a top substrate surface and a bottom substrate surface. The substrate includes a plurality of tiles extending outwardly from the top substrate surface of substrate. The tiles having a top tile surface and a bottom tile surface. The tiles and the substrate are integral and formed of a single piece of material. Each tile is connected to the substrate at a connection area. Each connection area projects upwardly from the top substrate surface of the substrate and includes a bottom connection edge connected to the top substrate surface of the substrate at a first angle and a top connection edge connected to a bottom tile surface of one of the tiles at a second angle. The tiles form an optical image on the panel.
