The creator only published part of this prompt; see the original post for the rest. What follows is the published part.

I wanted to see if beautiful destinations could become playable 3D experiences. Annecy, France became the prototype: a boat journey through canals, bridges, waterfront, and the mountain lake, built with Claude Opus 5.5 using Three.js + TSL.

I trimmed the navigation footage for the sake of keeping the video short and the post below below has a slightly longer version. The whole workflow behind this is simple:-
- Explained the concept to Opus and asked it to list some ideas.
- Shortlisted one and asked it to generate a prompt, with tech stack directions.
- Thats it, needed few iterations and is still a work in progress with few issues needing ironing. 
- The audio effects were added by Opus itself.
