That's really cool, thanks for sharing!
If I can give a little suggestion: on your linshare website (https://www.linshare.org/fr/accueil/), some elements are animated when the user scrolls down. This looks cool, however the animation is really too slow, making it hard to follow the text being introduced.
Reducing the animation duration to an half of its current duration could probably help a lot, and if that seems too fast, then maybe reducing the amount of transormations applied to animated elements may be better!
