  "brief": "The canvas displays a cutaway, three-dimensional cross-section of a running combustion engine. The viewer observes the complex mechanical heart of the engine: pistons move vertically within their cylinders, transmitting force down the connecting rods. These rods articulate visibly as they transfer rotational motion to the crankshaft. The crankshaft, the central rotating component, spins dynamically, showing the precise mechanical relationship between the connecting rods and the engine's core structure as the engine cycles through its power stroke.",

  "statement": "This sketch renders a dynamic, three-dimensional cross-section of a combustion engine using p5.js's WEBGL mode. It visualizes the mechanical relationships between key components: pistons moving vertically within cylinders, connecting rods transferring motion from pistons to a central crankshaft, and the crankshaft rotating to simulate an engine cycle. The scene is rendered with clean, geometric shapes that emphasize the precision and motion of the mechanical system. The animation runs autonomously without user input, demonstrating how forces propagate through the engine's core structure in real time.",
