Abstract
A moiré pattern display sheet is defined by a surface, with the surface being configured to be curved. A first layer has a pattern printed thereon. The pattern comprises a series of visual elements in a first row that have been distorted at least in a first direction. At least some of the series of visual elements are printed to approximately follow an arc having a sweep angle associated therewith. A light steering optical layer overlays the first layer. The light steering optical layer comprises a plurality of parallel optical features which each have a width and which change the direction of the light and thereby provide a depth effect of the visual elements to a viewer looking through the light steering optical layer.
