A display includes one or more first relief structures. Each of the one or more first relief structures consists of a smooth first reflection surface and a plurality of protrusions or recesses, each top surface of the protrusions or each bottom of the recesses is a smooth second reflection surface parallel to the first reflection surface, each of the one or more first relief structures is configured to display a color as a structural color by emitting a plurality of wavelength components of visible light wavelengths in the same direction, and each of the second reflection surfaces has a height or depth relative to the first reflection surface in a range of 0.1 to 0.5 m.

A method of integrating a radial zoom effect with a complementary radial image transition effect includes integrating the effects such that the two blended radial effects share a common center, and thereby share common displacement paths during the perceived transition. In addition to the visual appeal of the effect, the invention also resolves operational incompatibilities between the practice of commercial photography and the practice of lenticular printing. A lenticular product is formed in accordance with this method.

A versatile system, kit and method for a printing kinegram imagery with inked stamps enables users to place such imagery at desired, arbitrary locations on paper or other substrates, particularly useful in arts and crafts projects such as scrapbooking, and the like. A stamp has a surface having a plurality of raised and non-raised regions to produce a coded, printed kinegram image on a sheet of paper or other substrate. An overlay sheet with transparent and non-transparent areas corresponding to the raised and non-raised regions of the stamp, such that when the overlay is placed over the coded printed kinegram image, and one or both of the coded printed kinegram image and overlay are moved relative to one another, an illusion of movement or animation is imparted to a viewer. At least a portion of the stamp is transparent to facilitate precise placement of the coded printed kinegram image.

Methods and apparatus provide for an improved visual and optionally tactile features on a visible element of an article, such as a consumer electronic device (e.g., a mobile electronic device, a mobile phone, a smartphone, a tablet, a phablet, a notebook computer, a laptop, etc.).

An article of artwork having multiple images selectively viewable in different light conditions, the article comprises a substrate and a first image applied to the substrate using a first marking material. The first marking material is viewable under ambient and incandescent light. A second image is applied to the substrate using a second marking material comprising fluorescent compounds which are viewable under ultraviolet light. A third image is applied to the substrate using a third marking material comprising phosphorescent compounds which are viewable when the article is in a dark environment.

A laminate structure along with one or more security features is disclosed. The laminate structure may correspond to an identification document, such as an identification card, and may include a core layer with one or more security elements established thereon. As light is emitted into the core layer, the light impacts one or more of the security elements and is re-radiated back out of the core layer, thereby providing an indication that the laminate structure includes the security elements and is, therefore, authentic.

A balloon comprises a printed display. The printed display comprises: a printed image layer; a blocking layer provided behind selected portions of the printed image layer; and a diffusion layer provided behind at least those portions of the printed image layer not backed by the blocking layer. The blocking layer acts to block illumination of portions of the printed image layer, such that the printed display provides a different appearance when lit primarily from inside the balloon to when lit primarily from outside the balloon.
