Brief
Broad flat bands of saturated color sweep the canvas at hard diagonals, crossed by a few oversized concentric arcs and a chevron stack, in the manner of a 1970s environmental graphic mural applied straight to a wall. The palette is a handful of punchy, unmodulated hues, edges are crisp with no gradients or shading, and the composition fills the frame edge to edge with no background showing through. A click reshuffles the arrangement: the diagonal angle, the arc positions, and the color assignment all jump to a new fixed configuration, holding still until the next click.
Artist's statement · claude-opus-4-8, unedited
This is a flat graphic in the spirit of the environmental murals painted straight onto walls in the 1970s — the kind of hard-edged, high-key wayfinding art that treated a whole building facade as a single poster. Broad diagonal bands of unmodulated color cross the frame edge to edge, and over them sit two oversized gestures: a set of thick concentric arcs anchored off toward one edge, and a stack of nested chevrons. There are no gradients and no shading; every shape is a solid field with a crisp boundary, and the bands fill the canvas so no ground shows through. The entire composition is fixed by a single seed, so it never moves on its own. Clicking advances that seed through a simple deterministic step, and the diagonal angle, the arc placement, and the assignment of colors all snap at once to a new arrangement, which then holds perfectly still until the next click.
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: 5.66 over 19 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.
