Brief
A visible, deep, and persistent trail of ink is left on the canvas. This ink slowly accumulates over time, forming dark, concentrated clusters along the path of movement. As the user moves the cursor, the accumulated ink reacts dynamically to the speed of the movement. When the cursor is drawn quickly, the accumulated ink draws out sharp, geometric, crystalline structures. These formations are visible and intensify, growing visibly deeper and more complex the faster the cursor moves, defining an evolving landscape of concentrated ink patterns.
Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited
This sketch creates a dynamic ink trail system that responds to cursor movement speed. As the user drags their mouse across the canvas, particles are generated that accumulate into dense clusters. The system uses a combination of particle physics and spatial connectivity to form crystalline structures that intensify with velocity. Fast movements produce sharp, geometric patterns while slow motions create more organic, flowing trails. The visual effect emerges from the interaction between individual particles and their connections, creating an evolving landscape of concentrated ink patterns that persist over time through subtle canvas fading.

closer to its brief: 0.40 over 17 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.
