Browser-based 3D Mumbai urban simulation in Three.js

My first test-run with Gemini 4 Argon... and I am genuinely speechless 🤐 I gave it a single master prompt to build "MUMBAI: THE LIVING CITY" — a living, breathing Mumbai 3D Urban Simulation in the browser. Instead of a basic wireframe, it engineered a full open-world digital twin with: ⇢ Custom GLSL shaders for the Arabian Sea & 24-hour Golden Hour / Queen's Necklace night sky ⇢ 100+ simulated Kaali-Peeli taxis, autos & BEST buses obeying traffic signals ⇢ Clickable 3D vehicles & local trains with live camera lock + authentic horns ⇢ A real-time Web Audio synthesizer playing Raag Yaman & Monsoon Lo-Fi beats All running at 60 FPS in a single HTML file. Wait till the sudden #MumbaiRains hits in the video! 👇 Try the live simulation yourself — link in reply!
