This software is a green-themed GNOME interface.
For those who may not know, GNOME is an international effort to build a complete desktop environment based entirely on free software. The project includes creating software development frameworks, selecting application software for the desktop, and working on the programs which manage application launching, file handling, and window and task management. GNOME is part of the GNU Project and can be used with various Unix-like operating systems, notably Linux, and as part of Java Desktop System in Solaris.
While originally standing for GNU Network Object Model Environment, the GNOME project puts heavy emphasis on simplicity, usability, and making things "just work". This emphasis shines through with Chlorophylux, as its clean design and easy installation makes it an excellent choice for those looking for a seamless desktop experience.
