Howl's Moving Castle with its machinery opened up

From the post

🚨 Fable 5.5 TESTING Part 5 🏰 I asked Claude to build Howl's Moving Castle — then open it up. One prompt: Make me Howl's moving castle and also show its internal machinery. I never touched Blender. 🤯 ⏱️ 133 minutes 💸 $12.37 in API costs 🤖 Claude Fable 5.5 Xhigh in Claude Code What it did on its own 👇 🔥 Hearth fire → boiler → 2-cylinder steam engine → 48-32-32-16 gear trains → cranks → 4 walking legs, every rod really linked 🦵 Solved the walk from the planted foot, so the body only moves when a leg pushes 🚪 8 hull panels swing open mid-stride for a live cutaway 🎻 Wrote an original waltz where every bar is exactly one footstep (1.4 s) 🔊 Synthesized every sound: steam chuffs, gear clatter at the tooth-mesh rate, iron footfalls 🐛 Caught its own bug: every camera lens was silently stuck at 50 mm, traced to Blender 4.5's new action slots ⚡ Found the grass eating 5 s of every frame and cut render time from 9.3 s to 4.2 s per frame 📦 35 s · 1080p30 · 1,050 Cycles frames · 101 parts · 131k triangles

Author’s claim. Posted before Fable 5.2 came out. The author called it Fable 5.5, the name rumors gave the next Fable. We can’t verify which model ran.
