TL;DR of the post, generated automatically.

A fan project turns a trading venue's features into a drivable 3D map, with live figures, a timed raceway, and other visitors shown as named cars.

• Build: No bundler or build step. It uses three.js r170 and 21 hand-written ES modules loaded under a strict CSP. The source is MIT on GitHub.
• World: Terrain and roads are generated. Twenty-five low-poly Blender landmarks load as glTF after the first frame, with box stand-ins until then.
• Trades: Each trade on the venue arrives as a crate off a conveyor, sized by notional, with a small physics model for falling, tumbling and stacking.
• Racing: Laps are validated on a Worker with speed ceilings, and the fastest trace comes back as a ghost that drives beside you.
