Now that I have your attention, I've made this and I've been unemployed for a very long time -due to health issues- but now I'm fine and I'm looking for a job, creative frontend development in TypeScript is my specialization. Remote preferrably - European timezones. My email is in my HN profile if anyone's got any offer it would be amazing. Tysm everyone!
The animation player is made by the AI and there have been many optimization passes but the AI did them so I can't help you really with that question. I'm using GPT 5.5. I initially tried Three.js but it was way too slow, so I went building shaders directly. I figured the fastest paths will need to be tailored to the use-cases and a framework is good for humans at the expense of performance but since now we can just write the specific code directly that's better.
