Metacity

A window manager for GNOME, with a focus on simplicity and usability

rather than novelties or gimmicks. It uses GTK+ 3 for drawing window frames,

so that it inherits colors, fonts, and so on from the GTK+ theme. Its author

has characterized it as a boring window manager for the adult in you.

Many window managers are like Marshmallow Froot Loops; Metacity is like Cheerios.
