Brief

The composition begins with overlapping planes of deep, soft, and richly saturated color, reminiscent of abstract fields. Over time, these layers appear to slowly degrade, flaking away through a process of visible erosion. As the overlying color recedes, it reveals underlying crystalline geometries beneath the surface. These sharp, defined patterns resemble salt residue magnified at a microscopic scale, providing a stark, crystalline contrast to the surrounding deep, blurred planes of color.

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

This sketch explores the slow degradation of richly saturated color layers into crystalline structures. Deep blue and purple planes slowly shift and erode over time, revealing sharp geometric forms beneath. The effect is achieved through layered drawing operations where colored rectangles gradually fade, particle systems simulate erosion, and geometric crystal shapes emerge from the shifting surface. The viewer observes a continuous transformation from soft, blended color fields to defined, microscopic crystalline patterns, suggesting geological processes of erosion and mineral formation.

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