The laptop uses the Sugar graphical user interface, written in Python, on top of the X Window System and the Matchbox window manager. This interface is not based on the typical desktop metaphor but presents an iconic view of programs and documents and a map-like view of nearby connected users. The current active program is displayed in full-screen mode. Much of the core Sugar interface uses icons, bypassing localization issues. Sugar is also defined as having no folders present in the UI.
