FVWM-Crystal is a theme for the FVWM window manager. It uses GUI tools to edit the look of windows, instead of the use of editing a text file in FVWM. It creates a desktop environment using FVWM as its window manager and main core.
It features flexible window decorations, and a file manager may be optionally used to display desktop icons, ROX-Filer and Nautilus are supported for this task. FVWM-Crystal has user interface integration for some terminal emulators such as xterm, aterm and urxvt, for a tray system named stalonetray, for various music players - among them Audacious, MPD, Quod Libet, XMMS and XMMS2 - and for the video/audio player MPlayer, to the point where it can control these components. FVWM-Crystal makes use of semi-transparency. Almost everything on the default desktop is semi-transparent.
There is also a menu system that has an extensive default configuration but may be customized and extended by each user to fit personal requirements.
The deep-level configuration of the resulting desktop environment is predominantly achieved via Python scripts.
Chief developers of FVWM-Crystal are Maciej Delmanowski and Dominique Michel.
