For those wondering about the name, it has a fun story behind it: https://en.wikipedia.org/wiki/Sosumi

Jim Reekes talking about this in a deleted scene from the documentary Welcome to Macintosh: https://www.youtube.com/watch?v=k4J8AF25PjA

There's also a episode on https://www.macintosh.fm about the topic that I can recommend.

When I was a kid I used Sosumi as my chime on the apple IIGS!
