iDesk gives users of minimal window managers (like fluxbox, pekwm, windowmaker...) icons on their desktop. The icon graphics are either from a PNG or SVG (vector) file and support some eyecandy effects like transparency. Each icon can be configured to run one or more shell commands and the actions which run those commands are completely configurable. In a nutshell if you want icons on your desktop and you don't have or don't want KDE or GNOME doing it, you can use idesk.
