Red Star OS

Red Star OS is a North Korean Linux distribution. It is meant to act as a replacement to Microsoft Windows. Versions 1 and 2 are based on Red Hat Linux, while version 3 is based on Fedora 11. Early versions resembled Windows XP, and version 3 resembled Mac OS X. It was redesigned because of a 2013 photo of Kim Jong-un with an iMac at his desk, and he seemed to have liked the UI.
