Hey everyone! 👋 I vibecoded Principia because I've always struggled to visualize 'gnarly' physics concepts. Reading about Calabi-Yau manifolds is one thing; rotating one in 3D space with a bloom filter applied is entirely another. Under the hood, this is a heavy stress test for Google's Gemini 3 Pro model. I realized that LLMs are surprisingly good at writing GLSL shaders and Three.js logic if you give them the right 'thinking budget'. It's open-source and runs entirely in your browser. I'd love to see what concepts you try to visualize! Fun prompts to try: 'Double Slit Experiment with waves' 'Simulation of a wormhole traversal' 'Bose-Einstein Condensate' Let me know what breaks (and what looks cool)!
