Brief

The canvas is visually quiet until the user clicks anywhere on its surface. Upon clicking, a visible ripple emanates outward from the point of impact, accompanied by a soft chime. This ripple then undergoes a dramatic lifecycle: it collapses inward, triggering a concentric shockwave that rapidly radiates outward from the center. After the shockwave fades, the ripple vanishes, leaving behind a temporary, faintly visible solid ring imprinted on the surface before it finally disappears completely.

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

This sketch responds to user interaction with a visual and auditory ripple effect that demonstrates the lifecycle of a disturbance on a surface. When clicked, a ripple emanates from the point of impact, gradually expanding outward. As it reaches its maximum size, it collapses inward and generates a concentric shockwave that radiates back out from the center. The effect concludes with a temporary ring imprinted on the surface before fading away completely. The entire sequence is accompanied by a soft chime sound initiated by the user's click gesture. This minimal animation explores the physics of wave propagation through visual metaphor, with each stage of the ripple's evolution clearly defined and distinct in both form and timing.

The executor's own account of what it built, kept verbatim. A claim about the work, not a finding about it.
