IllusionOS is a Mock OS that consists of most of the projects I built during siege and than some. It is fully coded in C and it has applications that were also coded in C. I made this project in order to better understand the usage of header files and having multiple files of .c to work with within a project. .
This OS features apps like::

• NotSoSpammy: A email advertizing pyramid scheme
• SendyMaily: An email sending app
• NotSoNotFallty: A GUI based git Client
• NotSoNotSecure: A billboard Messaging app
• NotSoSpacy: An alarm Clock
• NotSoNotSpooky: A calculator that screams when you wanna do decimals
• ThreeEyedRaven: A magical Raven's weather app
• JustaGuiFramework: An app that lets you create GUI for your C software

• Execute the binary
• You'll be taken to a retro OS
• Click on the icons on the desktop or the dash to execute programs
• Use the programs as you'd normally use or check out the program's gh repo for more specific usage instructions
