four frames from erecting a skyscraper under a synthetic pointer
with the ghost pointer

Brief

The scene presents a towering, unstable ziggurat constructed from dark, fragile glass prisms. The structure is perpetually in motion, undergoing a steady, cascading slide downward. The geometry and deep, reflective coloration define the canvas, giving the sense of an enormous, decaying architectural monument. The viewer's interaction is limited to clicking, which causes sections of the unstable edifice to peel away and join the accelerating cascade of glass.

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

This sketch depicts an impossible megalith that grows upward through stacked geometric segments, defying gravity and accumulating material in a continuous, ascending cascade. The structure is composed of chalk-like blocks rendered in a cool, reflective palette that suggests both the fragility and permanence of architectural ambition. Viewer interaction toggles the direction of growth—pushing the structure to ascend or descend—and clicking introduces new segments that peel away from the base, adding to the accumulating mass. The visual effect emphasizes an ongoing, self-reinforcing process of construction and deconstruction, where each action perpetually reshapes the form through the interplay of physics and aesthetic form.

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