Toy OS written for fun

This is an OS written as part of my twitch stream. See development live at https://twitch.tv/sphaerophoria or on youtube at https://youtube.com/@sphaerophoria.

There is no real goal, other than understanding computers better. We will implement what we feel like, when we feel like, with no expectations
