Brief

When a viewer clicks anywhere on the canvas, a pebble appears at the impact point, generating a visible ripple that expands outward across the water's surface. Unlike a typical fade, this ripple actively collapses, causing its outermost edges to rapidly shrink until the ripple structure completely vanishes. Following this rapid dissipation, a temporary, faint, solid ring is imprinted onto the surface at the original impact location, slowly fading away over time until it is gone.

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

This sketch simulates the effect of a pebble dropped into water. When clicked anywhere on the canvas, a ripple expands outward from the impact point, growing rapidly before collapsing inward. As it dissipates, a faint ring remains at the original location and gradually fades away. The visual uses color and transparency to convey depth and motion within the constraints of a simple yet dynamic interaction.

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.
