This has been my (brooke) project to start our website from scratch, no external ~~dependancies~~ (Currently using simplex noise and of course the existing JS for the globe). Obviously much harder so far, but a nice learning experience.
Update: mostly started from the ground up, got some inspiration from https://codepen.io/prisoner849 and started trying to learn three.js, looks very interesting so far. It's a big mess and I don't expect most of this code to be moved into future releases but I think it looks cool and it's performant enough for the end user.
I still have some gripes about importing a library, it's obvious in the waterfall that it is measurably increasing page loads by almost a second, sometimes two.
