Inspiration: I was watching Billie Eilish s concert film HIT ME HARD AND SOFT, and during song Ocean Eyes there was a visual effect of waves. It sparked an idea — Could I build a web 3D simulation of ocean life while learning web development? And to explore the potential form of education or games.Honest caveats: the models are AI-assisted (rough pipeline: reference illustrations from Gemini → model generation in Rodin → cleanup in Blender → Draco/KTX2 compression for the web; writing and editing by human). They re not science-reviewed and have real flaws — transparent bodies and eyes especially — and some of the biology is approximate. I fact-checked the writing alone, so corrections are very welcome; there are source links on every card.Open source on GitHub. Happy to hear your thoughts, and to get into the pipeline or the science.
