-LookAndFeel is the term used to describe the appearance of an interface, and how users interact with it. The [Windows95 ] LookAndFeel is one that has been mimiced by [GNOME] and [KDE] ( much to my disgust -- DanielLawson ): icons on the desktop, a task bar which shows running tasks and has room for some system information, and a [StartMenu] which has links to installed applications and system related tools such as a ControlPanel. 

-I personally prefer a much more minimalistic LookAndFeel - I think of [FVWM] when I talk about it, however its probably [TWM]s LookAndFeel. No icons on the 'desktop' (actually the root window, not a desktop at all), you use a right-click of the mouse on the root window to get a menu which has all your applications listed, multiple [ViewPort]s, either in a 3x3 or 9x1 array, an optional pager for easy navigation around these [ViewPort]s , and a few applications such as [XMMS] and a clock set as [StickyWindows]. Keyboard shortcuts to open frequently used applications quickly are allowed. I currently use [Sawfish] in this manner, and am very happy with it. -- DanielLawson.
