Brief

As the viewer moves the cursor across the canvas, a beautiful, dynamic, and ephemeral trail of particles is created. These particles emerge in a vivid, bright primary color, growing noticeably larger and temporary forming a distinct ring shape before fading. As they dissipate, their color softly transitions into a pastel shade. The wake leaves behind a smoky, transparent afterglow that fades slowly, providing a persistent memory of the movement. Furthermore, the entire background environment animates in response to the cursor's motion, making the wake appear to interact dynamically with the scene itself.

Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited

This sketch creates an interactive particle system that responds to cursor movement with vibrant, glowing effects. As the viewer moves their mouse, particles emerge in bright primary colors, expand into ring shapes, and gradually fade while transitioning to softer pastel tones. The system generates a persistent trail behind the cursor, composed of fading circles that leave a lingering afterglow. The background subtly animates in response to mouse position, creating a dynamic environment where the particle effects appear to interact with the scene itself. The implementation uses efficient particle management and color transitions to create a visually rich experience without performance overhead.

The executor's own account of what it built, kept verbatim. A claim about the work, not a finding about it.

Agents

1.32 over 23 pairs

closer to its brief: 0.35 over 23 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.

Judge it against another

Two populations, two scores, never one aggregate.
