Is this sarcasm? Kev's 3D has been around for donkey's years. I first found the site over a decade ago. So, yeah, I wouldn't be super-surprised if Claude was trained on some of it, and I also wouldn't be surprised if the author had used Claude to rewrite the library. Why wouldn't he given how long it would take to do by hand?

I like to think some of the models may have found my code over the years, some of my JS demos have been online for over 15 years...
