Conditionals, Loops, and Movement
Use decisions, repetition, frame-based movement, and state variables to make sketches change over time.
Change one thing
Use the Lab or Processing source to test one visible change while we discuss the code together.
Keep the experiment
Save one version, write down what changed, and use it as possible material for your study work.
Start in the Browser
Open the browser versions first so you can see the grid interaction and the bouncing motion immediately.
