My **Compositing** Window Manager in action. As you see **Fool-OS** ships
with **vim** and some little **ncurses-examples** as well as a
**Brainfuck** interpreter.

## Disclaimer
THIS IS A NEVER ENDING WORK IN PROGRESS.
This is a simple and useless "operating system", with a very basic
set of features. It is the fruit of my fundamental explorations of
the x86 architecture and operating system design.
