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.
Ice Sound Manager was designed to ease the management of sound events, sound themes, and the IceSound server in the IceWM window manager. It is also intended to be an improvement upon the noble but primitive icesndcfg. The main improvements over icesndcfg include a support for sound event "themes", more comprehensive help, easy management and configuration of the IceSound server, a cleaner GUI interface, automatic starting of the IceSound server, and a more conservative approach to disk space usage.
