Jelly Castle · 3D Interactive Diorama

3D Scene

Single-file WebGPU jelly diorama: a wobbling jelly lake with a cliff-side fairy-tale castle, waterfalls cascading into the lake and continuing inside the jelly, a royal galleon sailing the perimeter, fireworks, drawbridge controls, time and firmness sliders—approximately 18 seconds. Screen recording compares Claude Opus 5.5 with GPT-6 Astra on the same prompt. Perfect for 3D interactive showcases and model comparison short films.
