Despite being on Firefox and seeing the effects half-working (at least we get performance ;D), this looks like the best implementation I've seen up until now (for some reason I was researching it a lot the last few days).

What I loved most though is the website design and the carefully crafted interactive visualizations! For me, they're on the same level as those of Bartosz Ciechanowski and Josh Comeau. I really want to see the source code...

Trust me, you don't want to see the source code right now. But I'll do another article and possibly open-source a library of it.
