Opened an AI Studio export expecting a broken toy and found a working weather engine hiding behind scaffold cruft. IsoGlobe Weather runs a two-step Gemini 2.5 Flash pipeline — Google Search grounding to fetch live conditions, then a second structured JSON call that generates a 12×12 isometric city grid with location-appropriate architecture, color palette, and glass dome tint. The Three.js scene renders procedural buildings with window textures, parks with deterministic trees, water features, roads, and a full particle system for snow/rain with accumulation on rooftops. All inside a physically-based glass sphere with clearcoat, transmission, and tinted refraction. Deleted the import map, cleaned up Tailwind CDN references, and had it rendering in the browser within minutes.
