## Made by AI

- Made with: Claude Opus 5.5
- How we know: X post (2026-09-26, Chinese): 'Making a game reward animation with Opus 5.5 is also very good! It originally generated 2D SVG icons; then I had it change to this 3D effect and optimised the lighting. This is the first, treasure-chest version.'
- Human role: Creator first got 2D SVG icons, then asked for this 3D look and better lighting; prompts shared in a follow-up.
- Pipeline: Opus 5.5 → code-rendered game UI animation → 15-second clip
- Series: Code-rendered film (LLM writes the program that draws every frame)
