Abstract:
1. A panel, the panel comprising: a first surface having a central portion and at least two peripheral portions adjacent opposite sides of the central portion; a second surface that is opposite and in a plane substantially parallel to the first surface, the first and second surfaces defining two opposing and spaced apart side edges of the panel; the central portion having a first surface topography defined by a first plurality of design elements, the first surface topography defining a first change in thickness among the design elements of the central portion, the first change in thickness being a difference between a maximum thickness of a thickest one of the design elements of the central portion and a minimum thickness of a thinnest one of the design elements of the design elements of the central portion, wherein the thickness is measured from the first surface of the panel to a distal surface of each design element along an axis that is substantially perpendicular to the first and second surfaces; and each of the two peripheral portions having a second and third surface topography, respectively, wherein the second surface topography is defined by a second plurality of design elements and the third surface topography is defined by a third plurality of design elements, the second and third surface topographies being substantially similar, the second surface topography defining a second change in thickness among the design elements of the second plurality of design elements, the second change in thickness being a difference between a maximum thickness of a thickest one of the second plurality of design elements and a minimum thickness of a thinnest one of the second plurality of design elements, and the third surface topography defining a third change in thickness among the design elements of the third plurality of design elements, the third change in thickness being a difference between a maximum thickness of a thickest one of the third plurality of design elements and a minimum thickness of a thinnest one of the third plurality of design elements, wherein the first surface topography is substantially different from the second and third surface topographies and the first change in thickness is substantially greater than the second change in thickness, and wherein the design elements extend outwardly from the first surface.
