Crystal OS is an operating system (currently just a kernel though) written in C. The aim of Crystal OS is to use and build on the UNIX philosophy that each program within it should do one thing well, not many things with problems. Each program should be able to work with other programs or be operated by the user in a terminal. The goal is to streamline the processes required for this to happen, but also build a fairly user-friendly and extendable terminal. At this point, a desktop environment is not being built or even planned, but once the main goal has been achieved, it is a possibility.
