Our main idea was to generate a 3D-digital software instrument where multiple users interact it though pressing a key and

activating the balls, initiating the flow of balls dropping down to the flat plane and making sounds.

Pressing a button or a key generates the movement of the ball, then a tone.

The generated ball starts traveling down to the plane and bouncing against the perimeter of the window and the surface.

More balls, more sounds: less balls, less sound: A visuo-auditory less and more analysis.
