The curator's reviewA real-time WebGPU snow world built end-to-end by Claude from a written spec: walk a field of wind-carved snow, cast ice spells, surf the dunes. No engine, no artist, one prompt document.

What came back is a hooded figure alone on a snowfield with volumetric sun haze, sastrugi carved by a prevailing wind, and footprints that persist behind you. I pressed one key and an arc of ice erupted from the ground. From the maker of a desert twin - a series of worlds prompted into existence.
