A colorful dazzling artifact includes supporting base, the supporting base being formed with a first opening and having an interior in which at least one light-emitting component and more than one light-transmitting vision window are arranged; a water-lamp main body, the water-lamp main body being arranged in the first opening of the supporting base, the water-lamp main body being of a hollow light-transmitting three-dimensional shape, in which a thick flowable liquid is received and hermetically enclosed; and at least one pattern decoration layer, the pattern decoration layer being fit inside the supporting base and corresponding to the light-transmitting vision window. Further, an ornamentation object and glitter powder may be arranged in the water-lamp main body. A rotating mechanism is provided to drive the ornamentation object to rotate and also to drive a liquid to flow so as to bring the glitter powder to flow therewith.

A suspended system with orientation control. The system may have a frame, a sign attached to the frame, a plurality of sensors, at least two thrusters, and a microcontroller operatively coupled to the plurality of sensors and the thrusters. The frame is configured to be suspended from a support, and the sign is configured to display a graphic. The plurality of sensors is configured to track an orientation of the frame. The thrusters are configured to adjust the orientation of the frame. Each of the thrusters may have an axis oriented in a direction perpendicular to the frame. The microcontroller is configured to receive a selected orientation of the frame, receive the current orientation of the frame from the sensors, compare the orientation of the frame with the selected orientation, and control the thrusters to adjust the orientation of the frame into the selected orientation.

A display medium that is able to arbitrarily change the display of recorded optical image information even when viewed from the same field of view, and an image display method that uses that display medium. The display medium includes a diffraction structure section on which optical image information is recorded, a chromic device that controls the reflection and transmission using voltage, and a power supply that is connected to the chromic device.

A multilayered printed matter includes a group of print layers formed on a medium. The group of layers include a front layer and a back layer on which patterns are printed, a white layer, and a black layer. The white layer is interposed between the front layer and the back layer to conceal the back layer to be invisible from the side of the front layer. The white layer reflects incident light from the side of the front layer to allow the front layer to be visible from the side of the front layer. The black layer is interposed between the white layer and the back layer to conceal the back layer to be invisible from the side of the front layer. In comparison between the black layer and the white layer that are equal in thickness, the black layer exerts a higher light blocking effect than the white layer.

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 drinking dramatization glass includes: a glass body being a bottomed cylinder body having a curved part that curves in the horizontal direction as well as a top opening; a fixing mechanism for fixing a video display device on the glass body; and an image aspect ratio control part for changing the aspect ratio of an image on the video display device. The drinking dramatization glass is configured to compensate for a horizontal distortion of images viewed through the drink in the glass.

Vehicle mountable holographic promoting system and method of use; system includes a body with light, mount, and controller in communication with a software application and the body. The body is mountable to the vehicle using mount. Mount can be removably attachable or otherwise secured to the roof of the vehicle. The controller controls the body such that the body can visually promote via an image display an item using the light—display region appearing to float on a plane above vehicle.
