OOOHhhh, a pulsating column of circles and gradually fading color gradient! The column can be stretched to fill the screen vertically as its component circles change shape and color over time. The sine-based animation can be manipulated to make different patterns and cycle through 5 color gradient ranges. This is another mode influenced by code from Zach Lieberman’s “Poetic Computation” talk. Looks cool with or without incoming audio.

knob1 = “Column height”
knob2 = “Column width“
knob3 = “Circle radius and column shape“
knob4 = “Gradient selector”
