Coral Reef Restoration Interactive Aquarium World

A playable miniature aquarium in a single HTML file. Players bring a bleached coral reef back to life by feeding fish, planting coral, and cleaning. It includes a fish school that follows the cursor, a sea turtle, an octopus, a shark, and day/night fluorescence. Built with three.js r170 WebGPU (WebGL2 fallback) and WebAudio synthesized sound. The prompt is a long, priority-ranked spec. Well suited to WebGPU showcases and calming short-form videos.
