Prefall 135 is an interactive audio-visual installation. It uses the energy of falling water to make watermills rotate and produce sound and graphics.
The sound is inspired in the sound produced by natural elements like wind and water. Every watermill has a specific function in this system, and the movement generated by the water falling will change parameters, creating this way some dynamic evolutions in the sound that comes from the installation.
Generated graphics are created according to the input of the camera that detects the rotation of the wheels.
