An item with a surface area creating an optical effect is such that the surface area with the optical effect exhibits at least two images (12, 14) separated a distance (d) from each other by means of a transparent layer of material (10). The distance (d) between the images 12, 14) and the distance (a) between two neighboring elements (16) forming the images (12, 14) are adjusted with respect to each other such that on altering the viewing angle (&agr;) the perceived overall image formed by the overlapping of the images (12, 14) is altered. A preferred application for the item lies in forms of packaging, packaging material, an aid to packaging, bonds or entry tickets with forgery-proof surface area and/or surface areas that have to meet high demands.
