# Matrix
|
||||
A matrix program to get some practice with C and the [ncurses](https://github.com/mirror/ncurses) library
|
||||
A matrix program to get some practice with C and the [ncurses](https://github.com/mirror/ncurses) library.
|
||||
|
||||
This project just recently turned 4 years old, and was one of my first C projects!
|
||||
I have been using it as a screen saver for my office all this time.
|
||||
|
||||
After staring at it running on this old CRT monitor in my office off of a Mac trash can (aka. 2013 Mac Pro)
|
||||
that is running Void Linux. I decided that it could do with a makeover.
