FVWM-Crystal aims to create an easy to use, pretty, but also powerful desktop environment for Linux or other Unix-like operating systems. It uses the following programs: FVWM as a window manager and "main core"; different ways to provide icons on the desktop including support for many file managers and custom commands; xterm, aterm, mrxvt, or urxvt as terminal emulators; MPD or XMMS2 as music players (there's built-in support for controlling these programs), and several other tools for different functions, like setting a wallpaper or taking screenshots.
FVWM-min is a minimal standard configuration for FVWM which provides a sane and functional set of window manager defaults. It configures FVWM to a very clean and functional state, then gets out of your way so you can do your work. The basic idea is that after installation, it should be usable enough for you to start productive work in it immediately. Styles are included for customizing the look, and are applied with a small shell script.
feed2wmmenu is a tool to generate X11 window manager menus from RSS, ATOM, or other news feeds. It was inspired by "fvwm-menu-headlines", which generates static refreshed FVWM menus from RSS or other kinds of news feeds. The drawback of the FVWM related script is the use of simple regular expressions. feed2wmmenu polls the feeds using curl, utilizing the Last-Modified header so that the feeds are potentially not fetched if they didn't change since the last poll. It produces diverse output formats by using corresponding XSLT stylesheets.
wmsupermon is a universal monitoring dockapp. It can be used to monitor CPU usage, disk I/O, memory usage, swap, filesystems, space utilization, network traffic, wireless link quality, CPU frequency, CPU temperature, fan speed, voltages (without requiring lm_sensors), battery status (with actual, not "reported", discharge rate), traffic from your router, or anything else. It can open and maintain many dockapp windows with one dockapp process.
Felidae is a collection of modules for Fvwm. FvwmStorage lets you define variables, load and store them from/to files, and execute any fvwm command using them. It is especially useful to interactively change the fvwm configuration. FvwmWallpaper lets you change your X wallpaper from within Fvwm. It tries to find the best way to display your picture and resizes it if necessary. FvwmXMMS lets you control XMMS by sending commands to this module. FvwmOsd lets you display an on-screen display on your X display. FvwmOsd is organized in different "channels", each of which you can configure and use independently of the others.
