AKFAvatar AKFAvatar is a fancy graphical user interface for applications, where an avatar appears on the screen and tells things to the user via a speech bubble. There can also be recorded audio files, so that the user even can hear what it is saying.

With AKFAvatar you can easily write cross platform applications in Lua. Lua scripts don't even need to be compiled for the target platform. It has an interface for C programs, which can also be used for Objective-C or C++. Furthermore there are bindings for Free Pascal and GNU-Pascal.

AKFQuiz 'AKFQuiz' lets you make your own quiz games, learning exercises or psychotests. These can be used with grquiz in a graphical environment, or with scrquiz on the text-console. There is also a line oriented variant, linequiz, which can be used as a backend. A CGI-variant, cgiquiz, can be installed on a Web server to offer exercises via Internet or a local network. Or you can use mkquiz, which generates an HTML-file for to use with JavaScript. Those can then be published using any web-space provider.

Aetherspace 'Aetherspace' is a project to produce multiplayer game that blends several different game genres. It is being developed by gamers as a way to learn programming. These games are currently under development and, while fun to look at, are not considered playable yet.

BibleTime BibleTime is a powerful cross platform Bible study tool. It uses the SWORD programming library to work with Bible texts, commentaries, dictionaries and books provided by the CrossWire Bible Society.

Big Daddy's Math Drills Big Daddy's Math Drills is a cross platform set of simple text based drills in basic addition, subtraction, multiplication and division tables featuring programmed instruction, adaptive learning, and user profiles.

Bingo-cards 'bingo-cards' lets you create number, word/letter, and picture bingo cards. They can be used for entertainment in the car, in a classroom (for example, to teach the element symbols for the Periodic Table), or just with your kids. You can also create cards with little pictures of everyday objects, then call the names out in Spanish, French, Italian, or German (or whatever you fancy).

C-Graph GNU C-Graph is a tool for visualizing the mathematical operation of convolution underlying natural phenomena susceptible to analysis in terms of engineering signals and systems theory. "C-Graph" is an abbreviation for "Convolution Graph". The package is derived from the BSc. Honours dissertation in Electrical Engineering "Interactive Computer Package Demonstrating: Sampling Convolution and the FFT", Adrienne Gaye Thompson, University of Aberdeen (1983). The package computes the linear convolution of two signals in the time domain then compares their circular convolution by demonstrating the convolution theorem. Each signal is modelled by a register of discrete values simulating samples of a signal, and the discrete Fourier transform (DFT) computed by means of the Fast Fourier Transform (FFT). GNU C-Graph is interactive, prompting the user to enter character or numerical values from the keyboard, dispensing with the learning curve for writing code. The software will be useful to students of signals and systems theory. C-Graph is written in contemporary Fortran. You can find pre-GNU development versions at: <http://codeartnow.com/code/download/c-graph-1/c-graph-version-2-preview>. Adrienne Gaye Thompson is the sole author of GNU C-Graph and looks forward to sharing further development with the FLOSS community.

Cce-interact Interact is an online learning and collaboration platform designed with the intention of making it easy for students and lecturers to interact online. It focuses on constructivist and Vygotskian views of teaching and learning. The system has been in use at the Christchurch College of Education (New Zealand) for approx 18 months now, supporting approx 1000 sites and 3500 students. Interact lets content be shared between course sites, so a lecturer can have the same content in many course, but only needs to update it in one place. Students and Lecturers can access all new course material and forum postings from one central place (no need to check every forum for new posts). Students can be given control of 'group' areas to add and manage their own material. Additionally, the system is flexible enough to be used as a full intranet/portal and not just for online course management

Charlearn This program is meant to help you learn to recognise foreign characters, taking just a few minutes each day. It remembers which characters you have recently found difficult and what you confuse them with. It uses a simple HTML user interface, the appearance of which can be customised by user-supplied stylesheets or normal browser customisation.

Claroline Claroline is a Web-based e-Learning platform that lets users or institutions host courses administered by professors or teachers through the Web. It features a quiz generator, calendar, file manager, forums, group area, course description, and more. It is available in 12 languages: English, Finnish, French, German, Italian, Japanese, Spanish, Danish, Swedish, Polish, Thai, and Chinese. The same server can host courses in different languages.
