Brightside extends GNOME window manager

Brightside is a small utility for extending the functionality of Metacity, the default window manager for the GNOME desktop. Now at version 1.4.0, it currently offers two mutually exclusive functions: corner actions that are activated when the mouse cursor moves to one of the desktop's corners, and scrolling with the mouse between desktops.

Although its home page has been down recently, Brightside is widely available in the repositories of major distributions. A wiki for the project has been registered with -- although no content or contact information has been added yet -- so the project may be in the process of moving.
