Abstract
Abstract A decorative article, and method, wherein a shaped mass of transparent material is embodied within a block of the same material so as to provide a shaped interface. Selected regions or areas of the interface are conditioned with light reflective material so as to render visible selected portions of the otherwise invisible interface, thereby achieving a three dimensional display having a shape controlled by the shaping of the interface but whose quality or artistic content is controlled by the conditioning of the interface.
