Laser lines at 635 nm or longer (ideally 647 nm) are preferred for red, giving energy-efficient, bright, rapid-motion images with rich, full film-comparable colors. Green and blue lines are used too—and cyan retained for best color mixing, an extra light-power boost, and aid in speckle suppression. Speckle is suppressed through beam-path displacement—by deflecting the beam during projection, thereby avoiding both absorption and diffusion of the beam while preserving pseudocollimation (noncrossing rays). The latter in turn is important to infinite sharpness. Path displacement is achieved by scanning the beam on the liquid-crystal valves (LCLVs), which also provides several enhancements—in energy efficiency, brightness, contrast, beam uniformity (by suppressing both laser-mode ripple and artifacts), and convenient beam-turning to transfer the beam between apparatus tiers. Preferably deflection is performed by a mirror mounted on a galvanometer or motor for rotary oscillation; images are written incrementally on successive portions of the LCLV control stage (either optical or electronic) while the laser “reading beam” is synchronized on the output stage. The beam is shaped, with very little energy loss to masking, into a shallow cross-section which is shifted on the viewing screen as well as the LCLVs. Beam-splitter / analyzer cubes are preferred over polarizing sheets. Spatial modulation provided by an LCLV and maintained by pseudocollimation enables imaging on irregular projection media with portions at distinctly differing distances from the projector—including domes, sculptures, monuments, buildings; waterfalls, sprays, fog, clouds, ice; scrims and other stage structures; trees and other foliage; land and rock surfaces; and even assemblages of living creatures including people.

Devices for producing waterfalls, which provide a decorative effect in pools, spas, bathtubs, and sinks. The devices include a water inlet, and a water chamber connected to the water inlet. An elongated water outlet is connected to the water chamber, such that water exiting the water outlet forms a waterfall-type flow. In one arrangement, a light chamber including at least one lamp is included. The light chamber has a window which allows light generated by the lamp to shine through the water outlet. In another arrangement, the elongated water outlet is provided on an outlet insert, the insert and water chamber having complementary inclined surfaces such that the outlet insert may be positioned at varying distances from the water chamber. In a further arrangement, a plurality of pins are located at the egress of the water chamber, the pins acting as baffles to the flow of water through the device.

The invention discloses a rotary waterfall shower comprising a hollow body, transversely arranged vane wheels, a front cover arranged on the front end of the body in a sealing way and a water division member which is arranged in the body in a sealing way and can cause the vane wheels to rotate, a pinion wheel is fixedly arranged on the front end of the vane wheels in an axial direction and is meshed with output gear wheels distributed in a central symmetry way, and each output gear wheel can drive one rotary water discharge component arranged on the front end of the front cover to rotate horizontally. Water sprinkled out from the water outlet of the rotary waterfall shower can be dynamically rotated to form gainly clusters of spiral waterfall water blooms, and the shower has the effect of gentle massage.
