Abstract

The invention relates to an article (I) that in at least one region (2) consists of a transparent or translucent material, in particular of glass, wherein the article (I) comprises a dynamic moire pattern in the transparent or translucent region (2), and wherein the moire pattern comes about by superimposing at least two, preferably precisely two, laser-engraved grid structures (3), which at least in regions are visually separated from each other. The grid structures (3) are located: in different layers (4) inside the transparent or translucent region (2); or in at least one layer (4) inside and in a coating (5) of at least one surface of the transparent or translucent region (2); or in at least one first layer (4) inside the transparent or translucent region (2) and at least one second virtual layer (6) that is produced by reflecting the first layer (4) at a reflecting surface (7).
