Perplexity CEO Arav Srinivas shared an AI-generated demo recreating Union Pacific Big Boy No. 4014 — the world's largest operating steam locomotive — entirely in code.
- Rendered as a live isometric SVG with its own renderer
- 1,324 parts and 15,312 convex faces, built from Union Pacific's published figures
- Includes a 7-step operating sequence from cold boiler to 60 mph
A showy demo of code-only generation with no assets or 3D models.
