A method for appreciating water balls using a water balls appreciation device, including a water balls discharge device and a light irradiation device, the method including: discharging the water balls, using the water balls discharge device, from tips of a plurality of nozzles, disposed at predetermined intervals in the lateral direction, by applying vibration to flowing water, the discharged water balls falling downwardly and in substantially a vertical plane; irradiating the water balls, using a light irradiation device, with light, the light irradiation device comprising a high-speed projector having a refresh rate of 300 Hz or more; and projecting a continuous screen of the projector in the water balls in the vertical plane regarded as a virtual screen by properly using a frame displaying a screen or an image and a frame not displaying a screen, so that a blinking duty is 20% or less, whereby the water balls are visually appreciated in the projected area. Then, by changing the timing of light emission for passing light through the image, it is possible to appreciate the movement of the water balls that changes in various manners.

A visual partition system is provided. The system comprises a number of dry mist dispensers that generate a particle curtain comprising liquid micro-droplets. A gutter system collects liquid from the particle curtain, and at least one vacuum extractor is operably coupled to the gutter system. A liquid recirculation system collects liquid from the gutter system via the at least one vacuum extractor and returns it to the dry mist dispensers for reuse of the liquid.

A hybrid reflective-emissive display including an electrophoretic medium. The electrophoretic medium includes two types of oppositely-charged, and differently-colored, particles in a fluid. The electrophoretic medium is disposed between a front light-transmissive electrode and a rear electrode including a plurality of apertures, such as a hexagonal grid. The electrophoretic layer is optionally illuminated by a light source disposed on the opposite side of the rear electrode from the electrophoretic medium. A viewer can see either the first or second type of particle at the viewing surface, or one of the particles can be illuminated by the light source, thus emitting light the color of one of the particles.
