Claude turns lobster photos into a 6,809-part robotic lobster in one 82 KB HTML file

A developer prompted Claude with a brief and real lobster photos and got back an interactive 3D robotic lobster that stunned him.
Key points:
- No model files: all 6,809 parts (plates, servos, rivets, cables) are three.js code in a single 82 KB HTML page
- Photo-accurate anatomy: fat crusher claw on one side, slim cutter on the other, low-slung body on short legs, 0.97 m beaded antennae arcing over the claws
- 8 legs walk on live inverse kinematics, and every on-screen gauge (14 kg mass, 137 N knee torque per leg) reads from the same model that moves the parts
- Tail-flip escape: 5 tail segments snap under as the body pushes off the seabed
- The model caught its own bugs: red rendering as peach, feet sinking 22 mm into the floor, the tail clipping 217 mm through it mid-flip
The quoted article describes a free Claude skill that turns any machine into a 3D simulator with live gauges, sharing the setup and all 9 prompts.
