gDesklets is another great tool like Google Gadgets for bringing mini programs called desklets such as weather forecasts, news tickers, system information displays, or music player controls, onto your desktop, where they are sitting there in a symbiotic relationship of eye candy and usefulness. The possibilities are really endless and they are always there to serve you whenever you need them, just one key-press away. The system is not restricted to one desktop environment, but currently works on most of the modern Unix desktops (including GNOME, KDE, Xfce).
