Anything CAN be music, but it doesn't BECOME MUSIC until someone WILLS it to be music, and the audience listening to it decides to PERCEIVE IT AS MUSIC.
(Frank Zappa)
Elektor Oscillographics Demo
"This is a project from the Elektor magazine published in 1978 - its an electronic spirograph circuit that you plug into an oscilloscope to produce ever changing and immersive Lissajous figures. The outputs are dampened sinewaves - so you can actually hear these at the same time as driving the oscilloscope."
