How to build an "itiswhatitis" like landing page.

Hi guys

I'm trying to build a fun and interactive landing page similar to the "itiswhatitis" site that went viral on twitter 'bout a month ago. (I've shared a link to the site) The stack used was Next.js, Emotion, framer motion toolkit for the animations and hosting on Vercel. I'm not familiar with any of these and was wondering if anyone who is could help me out in figuring how to build this.
