Enlightenment, also known simply as E, is a free software/open source graphical interface system. It can provide an X Window System window manager for use with GNOME or KDE, or it can also be deployed as a substitute for a full desktop environment. Enlightenment has a rich feature set - extensive support for themes and advanced graphics without sacrificing good performance.
