Tone Galaxy is a generative sound experience, where each shape is on a mission to separate itself from most of the other Bubbles. At the same time, shapes are seeking out a subset of other shapes (determined by you!).
Shapes make sounds when they get too close to each other (at a distance relative to the size of your web browser). The tones that play are spread across four keys, based on the root tone (controlled by the tone slider). Each key features the same set of intervals of its root, but the root can be an octave, fourth, or fifth above the root tone.
Shape Galaxy was created by Chris Schnaars. You can find more info on Tone Galaxy at Github and more generative sound tools here.
