A mechanical heart pumping oil, built in Blender

From the post

🚨 Fable 5.5 TESTING Part 6 🫀 I asked Claude to build a mechanical heart that pumps oil. One prompt: Make a mechanical heart and show its insides, use blender. ⏱️ 106 minutes 💸 $12.35 in API costs 🤖 Claude Fable 5.5 Xhigh in Claude Code What it did on its own 👇 ⚡ Dead heart, one spark, then it warms up to a steady 72 bpm 🔧 Two pistons on a crankshaft, one full turn per heartbeat 🚪 The front shell unbolts and swings open mid-beat 🛢️ Golden oil, rising bubbles and a drip that splashes into a brass tray 🎻 Original score: every bar line lands on the "lub" 🔊 Synthesized SFX: valve slams, motor whine, 572 oil bubbles 🔍 Spotted white streaks in the glass cylinders, fixed the wrong cause first, then traced them to two hidden lights 📦 30 s · 1080p30 · 900 Cycles frames · 210k triangles

Make a mechanical heart and show its insides, use blender.

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.
