FIELD: physics.
SUBSTANCE: proposed device comprises first set of adjacent semi-translucent lenses on first side of inner lens (120) with axis (A) revolving about and translating along said axis. Second set of such lenses is arranged on the side of concaved outer lens (125). Light source (135) is arranged to direct the portion of light beam through inner lens (120) and, thereafter, through concaved outer lens (125). Motor (145) drives said inner lens (120) to oscillate it about and along axis (A) to transmit moving textured image for conversion via fixed concaved outer lens (125) to display it on a surface, for example, on ceiling, to simulate the moving fluid surface.
EFFECT: enhanced performances.
