After Three.js r187 came out, I wanted to see how far I could push it with Codex -> GPT-6 Astra.
Tbh, I'm amazed by the result.
This whole little city is built in @threejs, with no imported 3D models.
And more to come.
Full office in 3D with Claude Opus 5.5 + Blender...
A few reference shots in, 1,876 objects out, built in 8 prompts.
How it's set up:
01 / Connect Opus to Blender over MCP and send the reference shots.
02 / Set one camera to match the reference and lock it.
03 / Build the shell: walls, windows, blinds.
04 / Add the big furniture, check it against the reference, lock it.
05 / Fill one zone at a time with clutter: desk, shelves, sill, floor.
06 / Spend the detail where the camera looks most.
07 / Materials first, then match the reference light.
08 / Render, compare side by side, fix one thing per prompt.
The rule: the camera never moves, so what's still missing is obvious at every stage.
Opus builds and renders. You hold the reference and call the fixes.
Eight small prompts, one finished room.
It is becoming f*cking dangerous: one line in Claude Code builds a turbofan with 3,597 parts you can cut open and break
1. Install the open source skill (Node 22.20+): npx skills add AirsupHQ/machine-skill -g -a claude-code
2. Add Playwright in its folder: cd ~/.claude/skills/machine && npm i && npx playwright install chromium
3. Open a new Claude Code session in an empty folder and type: /machine a turbofan jet engine, the kind that pushes a widebody off the runway
4. Let Claude write down real dimensions, parts list and physics, then build it
5. Open the HTML file, drag the throttle, try explode, cutaway, x-ray
6. Hit the break button: it throws a fan blade and the solver computes the load the case has to hold
7. Film it from that folder with your file's name (needs ffmpeg): node ~/.claude/skills/machine/scripts/record.mjs turbofan.html out/turbofan.mp4
The makers' estimate: about an hour per machine
You get one HTML file: the makers' demo counts 3,597 parts, nearly all blades, yours will differ, and the physics is a small model, not CFD

We gave #Gemini 4 Argon a CAD engineer’s job: design real sunglasses.
One text prompt in CadXStudio → parametric 3D model, frame, hinges, lenses, all editable.
It’s not a finished product. It’s a fast first prototype you can keep refining.
Generating a city in Blender takes about 30 seconds now.
iCity builds roads, towers, parks and traffic procedurally — aimed at driving sims, city flythroughs and archviz context.
