This software is a modified version of the Clearlooks Glossy theme.
GNOME, the desktop environment Clearlooks Bright is designed for, is an international effort to build a complete graphical user interface that sits on top of a computer operating system entirely from free software. The GNOME project involves creating software development frameworks, selecting application software, and managing programs that handle application launching, file handling, window, and task management.
GNOME is part of the GNU project and is compatible with different Unix-like operating systems, particularly Linux, and Java Desktop System in Solaris. The name was originally an acronym for GNU Network Object Model Environment, but it is now deprecated. Simplicity, usability, and making things "just work" are essential values that the GNOME project emphasizes.
In summary, if you're looking for a cleaner and brighter desktop environment, Clearlooks Bright is a great choice. It is compatible with GNOME's goal of simplicity and usability, making it an excellent design for anyone looking for a hassle-free computing experience.
