Best retro-styled/Frutiger Aero/Y2K/Aqua clients?

I really enjoy retro aesthetics , especially the Frutiger Aero style. I'm also really interested in old macOS Aqua 's design language and Y2K aesthetics.

I am looking for the best clients that follow this aesthetical rules for federated socials. I'm mainly interested in Mastodon, but I also would love to see it on PieFed/Lemmy and Friendica (since old facebook style would be fitting).

Does anyone know if such a thing exists for modern OSs? Should I look for clients or for a web app stylizer? Thanks.
