Lot to unpack in the comment, but maybe to clarify from my end >
I'm not the author of most of the animations so far, only a tiny fraction is remade as of now, I just started building tooling for me to develop new / more useful animations or animations for icons that dont exist yet from the lucide lib.
The majority of animations was ported from animate-ui and lucide-animated (github.com/imskyleen/animate-ui, lucide-animated.com), mentioned in the attributions, also visiable on the bottom of each icon page.
The reason I worked on this was that these components were built for react, and we're on vue for all of our work projects (and I use vue for my private ones, too).
Then I added additional QoL features to make the icons easy to use, not conflict with static lucide icons you might already use, and fix various animation bugs I encountered.
Not possible time-wise without LLMs here, for this project I see them mostly as an enabler to make this possible :)
