Conceptual fountains, also known as a dancing fountain, is a type of animated fountain for entertainment purposes that creates an aesthetic design. This is achieved by employing the effects of timed sound waves and timed light against water particles. The water refracts and reflects the light, and in doing so, three-dimensional images can be produced.
Installations can be large scale, employing hundreds of water jets and lights, and costing into the millions of dollars, or in smaller household forms, where a budget of one thousand dollars is feasible. Musical features tend to be complex, and require a degree of mechanical, hydraulic, electrical, and electronic components out of view that might be as impressive to its audience as the show itself.
