SuperKaramba (From Portuguese and Spanish super caramba, that means approximately super gee or super cool) is a tool that allows one to easily create functionality enhancement modules on a KDE desktop. Currently, only Linux is officially supported, although it also works well on FreeBSD and NetBSD. This program is similar to gDesklets for GNOME, Yahoo! Widget Engine for Windows and Mac OS X, DesktopX for Windows, and Dashboard for Mac OS X and also the gadgets subset of Google Desktop for Microsoft Windows.
The interactive programs are usually embedded directly into the background and do not disturb the normal view of the desktop. The use of SuperKaramba is not limited to KDE, but certain libraries from KDE are required. SuperKaramba is included in KDE 3.5.
Theme writers create themes, or text files that define their widget. Then, they can optionally add python scripting to make their widget interactive. The possibilities are endless!
Here are just some examples of the things that can be done:
Display system information such as CPU Usage, MP3 playing, etc.
Create cool custom toolbars that work any way imaginable
Create little games or virtual pets that live on your desktop
Display information from the internet, such as weather and headlines
