As Confetti2: http://sccode.org/1-31X in which you heard only one oscillator at the time. In SuperCollider it is easy to use 100 oscillators at the same time, so while a distribution is made, you can hear sounds that correspond with all the values in the box. That doesn't swing at all, instead it gives a kind of Xenakis-like experience.
