Nostalgia Mode (Theme)

This is a suggestion: Nostalgia Theme/Mode

If you go to appearance and toggle this (in the same area that Dark and Light mode are), everything begins to look (and sound) like it came from the 2012's, Skeuomorphism designs, gradients, stuff like that.

It'd be a nice addition, also we do need another theme :o

If you need examples, all it takes is a Google Search :D
