The goal of the General Applet Interface Library is to give programmers a simple yet powerful applet interface. This library supports wmapplet/dockapps, GNOME 2 panel applets, and ROX panel applets. The applet programmer doesn't have to care about where the applet will be used, since the library handles that. Over 50% of the code in a dockapp and a GNOME 2 Panel applet does only one thing, setting up the applet window. With GAI, this can be reduced to just a few lines of code.
Genmenu can generate menus for Blackbox, Fluxbox, Openbox, Window Maker, and Enlightenment based on the program binaries found installed on a system. The list of programs to search for are contained within the script. Users can, to a limited degree, customize their menus via a set of interactive questions.
KNOPPIX is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI devices, and other peripherals. It can be used as a Linux demo, educational CD, rescue system, etc. It is not necessary to install anything on a hard disk due to on-the-fly decompression.
Pop3eye is a POP3 email notifier. It can be placed in a "dock", or use a regular or undecorated popup window. Regular expressions are used to filter email. It can display up to 20 partial lines of the email body in a tooltip window. It can monitor and display an unlimited number of accounts. You can choose to show messages using regular expressions, or delete messages from the server.
Sherman's aquarium is a screen saver, a GNOME panel applet, and a dock applet that provides an aquarium with fish and/or turtles. In applet mode, it can display lots of information, such as CPU load, temperatures, memory usage, and many other things. Both the applet and the screensaver are very configurable.
Ticker.app is just like a ticker, and is designed in the dockapp that is supported by X window managers such as Window Maker, AfterStep, BlackBox, and Enlightenment. It reads a file that is specified by the command line, and displays each line in a viewing area periodically. It rereads automatically when the file has been modified. If you run in a tail-mode, it ticks only the last line.
