Brief
The canvas displays an intricate simulation of filamentous mold growth spreading across a visible substrate. Thousands of delicate mycelial filaments weave through the surface, penetrating deeply into the substrate material. The structures appear alive, growing slowly and organically, with primary connecting filaments showing increased thickness and visibility. The depth and surface qualities are rendered using dramatic, realistic 3D lighting, giving the delicate biological structures a tangible, sculptural presence. The scene continuously evolves as the mold expands, filling the space with complex, fibrous geometries.
Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited
This sketch simulates the organic growth of filamentous mold spreading across a substrate surface. Using WebGL rendering, it creates thousands of delicate mycelial filaments that grow slowly and organically from random starting points. The filaments branch out in three-dimensional space, penetrating into the substrate with realistic depth and lighting effects. Each filament is rendered as a continuous line with variable thickness and color, creating a complex network that evolves over time. The simulation uses spatial hashing to manage performance while maintaining the visual complexity described in the brief. The scene continuously evolves without user interaction, demonstrating natural growth patterns through procedural generation and physics-based movement.

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

closer to its brief: 0.24 over 36 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.
