A transparent display device includes an image display bar in which a plurality of light-emitting elements are arranged, and a bar driving unit which moves the image display bar along a predetermined path and provides transparent display using afterimages resulting from the movement of the light-emitting elements, wherein the transparency of the transparent display using afterimages is determined by the equation, transparency (%)=((A−B)/A)*100, where A denotes the entire display area of the transparent display, and B denotes the area of the image display bar.

A display arrangement includes a base, a decorative shell having a front cover and a back cover, an elongated central post that is rotatably coupled to the decorative shell and fixedly coupled to the base, a light source disposed on the elongated central post and within the shell, such that the light is visible though at least one opening in the shell, a stem coupled to the shell and coupled to the elongated central post, the stem having a magnet on one end, and a coil configured to receive energy from a power source to cause an arcing motion of the magnet, the stem, and thereby the decorative shell. The display arrangement can include a second shell disposed horizontally above the decorative shell and coupled to the decorative shell, and can also include a third shell disposed horizontally below the decorative shell, and that is coupled to the decorative shell.

A coded image display and animation system with an illuminated shutter element device that permits the user, by placing individual coded image members and combinations of coded image members upon it, to create collages, puzzles and fantasy worlds that instantly appear to come to life and move realistically. Coded image members can be chosen and selectively repositioned, overlapped, and combined for varying displays and display effects. Larger, window-sized displays with or without coded image portions can be exploited, potentially to provide moving backgrounds, such as falling snow or moving clouds, upon which the coded image members can be positioned thereby permitting the user to create multi-member displays and animations, including animated stories and animated fantasy worlds. Coded image members and non-coded image members can have open portions for permitting the application of images or image portions by users, such as by erasable marking implements.
