   <p>Bridget Riley, a celebrated British artist, was a driving force behind the Op Art movement of the 1960s. Her work features geometric patterns that challenge the viewer’s perceptions and evoke feelings of movement or vibration. Her 1974 piece <em>Gala</em> showcases a series of curvilinear forms that ripple across the canvas, evoking the natural rhythm of the sine wave.</p>

 <p>In Chapters 1 and 2, I carefully worked out an object-oriented structure to animate a shape in a p5.js canvas, using the concept of a vector to represent position, velocity, and acceleration driven by forces in the environment. I could move straight from here into topics such as particle systems, steering forces, group behaviors, and more. However, doing so would mean skipping a fundamental aspect of motion in the natural world: <strong>oscillation</strong>, or the back-and-forth movement of an object around a central point or position.</p>
