Since I'm interested in working with balls I thought this ping pong piece is something to look at and ponder about. I don't particularly like or dislike this work. The artist explains (see below) the whole process and ideas behind his piece.
Sound Sculpture by Manuel Rocha Iturbide
The sound sculpture has 3 series of speakers that play 3 tracks with the sound of processes of ping-pong balls bouncing stochasticly, alternating with periods of silence, and with pure sinusoidal frequencies. The sound of each track alternates between each other so that the speakers sound at different times. The sinusoidal frequencies diffused through the speakers were calculated in order to be sympathetic to the natural tuning of the sculpture's alluminum plate, so that they make it vibrate and resonate. The effect of the vibrating plate over the ping-pong balls is that some of them bounce in a fixed point...continue here
