I checked the source code and found the following Javascript library:
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/1.20.2/TweenMax.min.js"></script>
I did some research and it seems that TweenMax has been replaced by GSAP.
Another way to easily find out what servers, libraries, etc. are being used on a website is by using the Wappalyzer Browser extension.
It would be great to see the animations you make. If you can, please post them in this forum.
