Brief
The canvas displays a dynamic, pulsating field emanating from a central point. Concentric arcs sweep rhythmically across the frame, varying in color and thickness to simulate the detection strength of different objects. The movement is continuous and cyclical, causing the entire display to gently pulse and rotate. The viewer's cursor directly influences the pattern; dragging the mouse across the canvas causes temporary, intense flares to appear, changing the density and brightness of the simulated radar echo field.
Artist's statement · qwen3-coder:30b-a3b-q4_K_M, unedited
This sketch creates a dynamic, pulsating radar-like field that emanates from the center of the canvas. Concentric arcs sweep rhythmically across the screen, varying in color and thickness to simulate detection strength at different distances. The entire pattern gently pulses and rotates over time, creating an immersive sense of motion and energy. When the viewer drags their mouse across the canvas, temporary intense flares appear that temporarily disrupt and intensify the field's density and brightness. These interactive elements add a responsive layer to the otherwise autonomous animation, making each interaction with the canvas change the visual dynamics in real-time. The work uses WebGL rendering for efficient batched drawing of the multiple arcs and point effects, all within the frame budget constraints.
The executor's own account of what it built, kept verbatim. A claim about the work, not a finding about it.

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.
