FVWM-crystal creates an easy to use desktop environment using fvwm2 as its window manager and main core. From another point of view its just a very powerful fvwm configuration.

A file manager may be optionally used to display desktop icons, ROX-filer and nautilus are supported for this task. FVWM-crystal furthermore has UI integration for various music players, among them xmms.

There is also a very powerful menu system that has an extensive default configuration but may be customized and extended by each user to fit personal requirements.
