Over the past few years, 3-D rendering in window managers has become a new trend in the desktop environment. OS X was the first to make fancy visual effects prominent in the way users interact with the windows in their desktop. Windows Vista has also jumped on the bandwagon with its Aero interface, though it has some performance issues to work out. Linux users do not have to feel left out if they too want their desktop to be a little prettier. Beryl (formerly Compiz) gives many customizable features for users that want 3-D rendering in Gnome, KDE, or other window managers.
