ShiftOS 4caacce50c ShiftOS 
ShiftOS is a game about evolving an experimental operating system called
"ShiftOS" from a completely black and white text based command line
based OS to a fully graphical operating system filled with advanced
features and beautiful colours. The level of customization will exceed
the levels of real world operating systems
