I had Claude Fable 5 build a walkable 3D Kyoto neighborhood in Three.js. Runs in the browser.
It's not a single street. There's a connected grid of alleys, intersections, and plazas you can actually wander through. Machiya townhouses, stone lanterns, cherry blossoms, paper lanterns glowing at dusk. A pagoda visible above the rooflines from different streets.
Golden hour and night mode toggle. WASD to walk. Mouse to look around.
Took two prompts. One for the initial build, one to fix the layout so it wasn't a straight corridor. Some areas still feel disconnected and disjointed, but for a browser-rendered 3D neighborhood from two prompts, it's not bad.
