In this chapter, we will shape up visual elements and implement visual structure together with code structure. Visual elements can evolve best when the idea is still under construction, and we can follow new inspirations from working with code. We will also dig a bit deeper in working with data structures and unleash new powers of Processing. To achieve this, we introduce four refinements here: “Randomness and Noise,” “MemoryDot,” “Using Computed Values,” and “Interaction.” Using these refinements, we can make big steps from the simple visual elements of the previous step toward solutions that match our idea even better.
