Source: Get to know Linux: Window Maker

Continuing with our introduction to old-school Linux window managers, I would like to bring to you Window Maker. The Window Maker window manager was designed to look and feel like the old NeXT GUI (which was spearheaded by Steve Jobs after he was forced out of Apple.) Window Maker is another entry in the long list of lightweight, snappy window managers that can bring new life to old computers. Window Maker is a very stable desktop for the Linux operating system and is often considered one of the most universal and useful window managers available.
Window Maker makes many changes to the standard desktop metaphor as we know it today. Gone is any semblance of a panel. Instead Window Maker offers a number of interesting features.
