I’m with my wife Bess (https://bessstillman.substack.com/) and my brother Sam, and crying, but it is okay. At the end of Lord of the Rings Gandalf says to the hobbits, "Go in peace!

My focus was not so much on pixel perfect, but instead on creating something that would also work and look aesthetically pleasing on modern systems, like with higher DPI monitors and such. So one of the the things I did was to recreate all the icons and symbols in SVG.
I tried posting it as a Show HN when I added XP and Mac OS 9, but it didn't get much attention. Maybe the title of the project isn't as catchy.
