About Neon Zenith
Fly a hover car through a rainy neon Kowloon, chasing time trials and hidden data shards.
Kowloon, 2077, raining. You pilot the KITE, a hover car, through a city of 9,373 buildings. On Temple Street it drifts like a car; in the sky lanes it holds altitude like a VTOL. Climb above the storm and you can land on a spire 1,418 m up.
There are four medal time trials (Market Dash, Sky Lane, Ascent and The Dive), 31 hidden data shards, a map with waypoints, a radio and free ride. Taxis, minibuses and buses keep left and stop at signals below you.
How Neon Zenith was made with AI
From the README: 'Built over a weekend in October 2026 with Claude Code running Claude Opus 5.5. I set the direction and reviewed every pass from screenshots and real-GPU frame timings; the model wrote the code, the TSL shaders and the Blender pipelines.' It runs on the Three.js WebGPU renderer with an automatic WebGL2 fallback.
Made by Bill Chan (billpwchan).

Tips for Neon Zenith
- Boost (Shift) while at speed to initiate a drift on Temple Street: corner speed is where medals are won.
- Use the map waypoints (M) to hunt the 31 data shards systematically instead of free-riding blind.
- The Ascent trial rewards climbing above the storm and landing on the 1,418 m spire: practice the landing, not just the climb.
