GNOME project has built a complete free and easy-to-use desktop environment for the user, as well as a powerful application framework for the software developer. GNOME is included in pretty much every BSD and GNU/Linux distribution and works on many other Unix systems.
It is a greatly improved user environment for existing GNOME applications. Enhancements include anti-aliased text and first class internationalisation support, new accessibility features for disabled users, and many improvements throughout GNOME's highly regarded user interface.
