Brief
A brightly colored marble is shown rolling through a deep, sculpted container. The viewer observes the marble following a curved, downward path starting in a narrow funnel, transitioning to a steep, angled slope, and finally widening out into a shallow basin at the base. The marble's movement is governed by realistic physics, causing it to roll naturally and bounce slightly as it navigates the varied contours and surfaces of the channel until it comes to rest in the collecting basin.
Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited
This sketch depicts a marble rolling through a sculpted container with physics-based movement. The viewer observes the marble following a curved path starting in a narrow funnel, transitioning to a steep angled slope, and finally widening into a shallow basin at the base. The animation demonstrates realistic gravity, bouncing, and friction as the marble navigates the varying surfaces of the channel until it comes to rest in the collecting basin. The scene is rendered using WebGL for 3D effects with lighting and shading that enhance the volumetric appearance of the marble and container geometry.
The executor's own account of what it built, kept verbatim. A claim about the work, not a finding about it.

closer to its brief: 1.32 over 41 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.
