A user testing Space Bunny in OpenCode says it turned a rough wireframe into a landing page that followed all seven handwritten notes. They also report a playable Three.js game that followed a hand-drawn level sketch and all ten written rules. The model then reportedly playtested jumps in Chrome and adjusted the physics until every lava stone was reachable. Other reported results included a moka-pot 3D model and a camera model with 67 labeled parts. An animated explanation of a circle’s area was “not perfect,” but still impressed the tester. The user supplied the prompts and images, while noting they did not know which model Space Bunny was.
