Play cool sounds based on stacking an interval. The circumference of the circle represents an octave, and each line is a note Overtones (the individual sine waves that add up to make a sound) are generated to align to the scale This lets you generate a microtonal/xenharmonic scale, which does not align with the twelve tones of Western music theory, but scales like this is common in other cultures. Try adjusting the generator slightly and playing chords.
