GNOME

Preferred license: GNU General Public License (GPL)
The GNOME project provides two things: The GNOME desktop environment, an intuitive and attractive desktop for users, and the GNOME development platform, an extensive framework for building applications that integrate into the rest of the desktop.
Actual source code produced by the student participants in Google Summer of Code™ for GNOME can be found here.
