Tested out the new Gemini 4 Argon + Claude Opus 5.5 combo by having them build a playable 3D Jurassic World island in WebGL. Argon handled the spatial layout and shaders while Opus wired up the camera controls—you can literally jump between the T-Rex Paddock, Brachiosaurus Herd, Pteranodon Cliffs, or just WASD free-fly around Mt. Sibo.
