A Reddit user built an interactive, browser-runnable Stonehenge scene with Claude Fable 5.2 (high effort) from a single prompt, shipped as a single HTML file using three.js.
The scene includes lichen-covered sarsens and trilithons, bluestones, the Heel Stone, instanced wind-swayed grass, real-time shadows, a sun following the summer solstice path, 144 low-poly visitors, and a full "as built" view.
