#331Hammered Copper

A hand-raised copper sheet: Voronoi cells tile the surface into shallow hammered dimples, and each pixel takes the outward-tilting dome normal of its nearest pit. That normal samples an inline procedural studio (a soft key softbox, a cool fill and a top-down ambient gradient — a matcap built in code, no texture), so every dimple catches the light from a slightly different angle and the plate erupts in shifting glints. A drifting low-frequency field lays green verdigris into the darker grout between pits for age. The key light orbits on its own so the sheet sparkles unattended; the pointer relights it and a press brightens the room.
