Curate, connect, and discover
I originally created a site skin based on this aesthetic about 2.5 years ago, but it was frankly pretty broken in a lot of ways. As I was looking through my list of site skins, I remembered this one and decided to revive it and make it a little more usable.
If you like it or want to try it out, you can find the CSS code over here on github, along with instructions for how to copy/paste it into a skin for your own AO3 profile.
(as always when I attempt a site skin, if you find stuff that's broken, you can let me know and I'll try to un-break it)
