  "brief": "The canvas displays a dynamic, three-dimensional cross-section cutaway of a running internal combustion engine. Viewers observe pistons moving within cylinders, driven by the simulated expansion of combustion gases. The connecting rods visibly rotate the crankshaft, while simultaneously, intake and exhaust valves open and close, demonstrating precise timing correlated to the piston\u2019s position. Colored fluids trace the timed flow through the intake and exhaust ports, illustrating the engine's continuous operational cycle.",

The crankshaft rotates via connecting rods, while intake and exhaust valves open and close in sync with piston motion. Colorful fluid streams trace the flow through intake and exhaust ports, illustrating the continuous engine cycle. The visualization uses WebGL for 3D rendering and includes subtle audio feedback that responds to a single user click.",
