Gnome is defined as " GNOME (pronounced
A window manger is, "A window manager is system software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are designed to help provide a desktop environment. They work in conjunction with the underlying graphical system which provides required functionality such as support for graphics hardware, pointing devices, and a keyboard, and are often written and created using a widget toolkit.
Few window managers are designed with a clear distinction between the windowing system and the window manager. Every graphical user interface which uses a windows metaphor has some form of window management; however, in practice, the elements of this functionality vary greatly. The elements usually associated with window managers are those which allow the user to open, close, minimize, maximize, move, resize, and keep track of running windows, including window decorators. Many window managers also come with various utilities and features: e.g. docks, task bars, program launchers, desktop icons, and wallpaper."

What is Compiz ?
(taken from Compiz README)
Compiz is an OpenGL compositing manager that use GLX_EXT_texture_from_pixmap for binding redirected top-level windows to texture objects. It has a flexible plug-in system and it is designed to run well on most graphics hardware.
Okay, this description isn’t really meaningful. In a nutshell, Compiz is a compositing manager, which means that it enhances the overall user interaction by adding fancy effects to your windows, from drop shadows to awesome desktop effects like the Desktop Cube or the Expo view.
Compiz can also be a window manager, which means that it is the software between you and your desktop apps. It enables you to move or resize windows, to switch workspaces, to switch windows easily (using alt-tab or so), and so on.
If you heard of Beryl or Compiz Fusion, it’s us as well ! Check the wiki page for more details on the (somewhat troubled) project history.
The latest release of Compiz is 0.8.6. A C++ rewrite has been announced on 24th December 2009 and is about (June 2010) to be released as a beta version. This is a major rework of the whole project, aimed at easing future development.
What was Compiz Fusion ?
(taken from AboutCompizFusion Wiki page)
Compiz Fusion is the result of a merge between the well-known Beryl composite window manager and Compiz Extras, a community set of improvements to the Compiz composite window manager. Compiz Fusion aims to provide an easy and fun-to-use windowed environment, allowing use of the graphics hardware to render each individual window and the entire screen, to provide some impressive effects, speed and usefulness. The first Compiz Fusion developer release was Compiz Fusion 0.5.2 on August 13th 2007, shortly after Compiz 0.5.2 was released. First stable release of Compiz Fusion is 0.6.0 released on October 20 2007.

Re: Compiz Addons: A script to install experimental plugins
... and they work wonderfully. Now ubuntu 11.04 is upon us (and congratulations to the Compiz team for the important role it plays in developing the Unity desktop), I am wondering if these dazzling plugins will be updated and made available in future releases of Ubuntu. I have tried to install them

"...Developers will be able to create extra ‘places’ for users to add to the ‘Dash’ and multi-touch functionality to the shell as a whole will be introduced using the uTouch framework.
Notably, Desktop Unity will use Compiz rather than Mutter for compositing.
"Unity is a shell for GNOME – it may not be GNOME-Shell but it is a shell for GNOME." Shuttleworth told the audience on the potentially contentious issue of this move being seen as moving away from GNOME.
"It’s healthy for GNOME for to have competition." he went on to say before iterating that developers are ‘in this together’...."
