Interesting! An option to view the CSS directly on the site would be useful. I'm curious to see how it works under the hood, but don't want to download the file since I'm on mobile.
Nice! Oh and the new samples are awesome! It actually looks super cool to see it in interactive elements.
Would love to see a write-up of how you made this work. I took a peak at the repo and I can see it's using a bunch of SVG filters, which I think is underutilized piece of tech!
Some feedback on the effect: I think the copper and the gold could use a bit more tweaking. The gold has a bit too much green, and the copper has a bit too much red perhaps? It looks kind of earth coloured.
