PCT No. PCT/EP96/03750 Sec. 371 Date Feb. 24, 1998 Sec. 102(e) Date Feb. 24, 1998 PCT Filed Aug. 26, 1996 PCT Pub. No. WO97/07994 PCT Pub. Date Mar. 6, 1997The present invention concerns an opto-mechanical system and method for obtaining scenographic and decorative effects on surfaces suitable as screens. The system includes a container of liquid, such as water and a movable planar element placed inside said container. An actuator is provided for variably displacing the movable planar element relative to the liquid to generate a variety of movements of waves above the upper face of the movable planar element, while a light source is placed relative to the container to project the movements of the waves onto the surfaces. The movable planar element can also be displaced manually. The system permits the creation of a great variety of wave design patterns due to the displacements of the movable planar element inside the container of liquid.
