Claude Opus 5.5 just built Minecraft.

In the browser. From a single prompt.

Noah Wachnick asked it to recreate Minecraft with advanced shaders, "as realistic as possible."

1 hour 37 minutes at max effort:

> block placement
> terrain
> realistic lighting and shaders

Here's a prompt to try it yourself. Bookmark this for later 

"Build a Minecraft-style voxel game in a single HTML file that runs in the browser.
- First-person controls: WASD, mouse look, jump
- Procedural terrain with hills, water and trees
- Place and break blocks with the mouse, 5 block types
- Advanced shaders: moving sun, soft shadows, ambient occlusion, fog, water reflections
- Smooth 60 fps on a laptop
Use Three.js from a CDN. Test it, fix every bug, then keep improving the visuals until it looks as realistic as possible."

Tips:
1. Set effort to max
2. Give it time, the original run took ~1.5 hours
3. When it's done, ask: "What looks least realistic? Fix it."
