ROX

ROX is a fast, user friendly desktop which makes extensive use of drag-and-drop.

Details
The interface revolves around the file manager, or filer, following the traditional Unix view that `everything is a file' rather than trying to hide the filesystem beneath start menus, wizards, or druids. The aim is to make a system that is well designed and clearly presented. The ROX style favours using several small programs together instead of creating all-in-one mega-applications.

Platforms
ROX runs on Linux, Unix and Mac OS X, basically anything vaguely Unix-like which can run GTK applications.

License
The software uses various licenses, but mainly GPL
