Turn audio amplitude into color. Every ‘trigger’ event places five nested circle groups on the screen in random positions. A nested circle group may have up to 50 circles. Each circle within the group represents one of the first 50 positions in the audio input array. The color of the circle is mapped to the audio amplitude for each position.

Knob1 sets the history length for the audio input: max left is ‘no’ history (displays the current audio) and max right averages the amplitude over the last 20 values (this looks the smoothest, but not as responsive as max right).

Things get fun when you set MIDI clock or notes as the trigger source – this will pick new locations and sizes of the circle groups. (The ‘trigger’ button works too for manual input)
