Brief
The canvas presents a detailed, mechanical cross-section of a combustion engine. Viewers see interconnected pistons moving within cylinders, coupled with complex, visible gear systems that translate rotational forces. The scene utilizes polished metals and bright internal components to highlight the energy transfer. These mechanisms are continuously and cyclically animated, demonstrating the power stroke and the resulting interconnected motion of the gears. The viewer observes the perpetual, dynamic working principle of the engine without needing any direct interaction.
Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited
This sketch presents a mechanical cross-section of a four-stroke combustion engine rendered in 3D using p5.js WEBGL mode. The visualization features interconnected pistons moving within cylinders, a rotating crankshaft, and multiple meshing gears that demonstrate the energy transfer and cyclic motion typical of internal combustion engines. The scene continuously animates without user interaction, showing how rotational forces are converted into linear piston movement through mechanical linkages. The polished metallic surfaces and detailed gear teeth create a realistic representation of engine internals, emphasizing the dynamic working principle through continuous motion.
The executor's own account of what it built, kept verbatim. A claim about the work, not a finding about it.

A Bradley–Terry score needs pairs; none has been judged.

closer to its brief: 0.12 over 37 pairs
Bradley–Terry over this population's pairs alone. 1.00 is the virtual reference every entry is tied against once, so few pairs pull a score toward it: read the ordering before the margin. Views and likes are engagement, not judgment, and are not in this number.
Two populations, two scores, never one aggregate.
