- FLIF is a novel lossless image format which outperforms existing image formats in terms of compression ratio. It works well on any kind of image (photographic, line art, computer graphics, etc.) and also supports animations. FLIF images (or animations) can be progressively decoded, which makes the format potentially very suitable for responsive web design. This is the reference implementation of FLIF, which includes a command-line tool (flif) to convert between FLIF and PNG/PNM/PAM, a decoding library (libflif_dec), an encoding library (libflif_enc), some scripts (gif2flif, apng2flif, raw2flif, ...), and a simple image/animation viewer (viewflif).
- FIM is a lightweight universal image viewer, mostly for Linux (but not only). FIM aims to be a highly customizable and scriptable image viewer for users who are comfortable with software like the VIM text editor or the Mutt mail user agent. It has been developed with Linux in mind, but can be built to run on several Unix systems or even on MS-Windows.
- Free Oberon
- Free Oberon is a cross-platform IDE for development in Oberon programming language made in the classical FreePascal-like pseudo-graphic style. Compilation of user-written programs is performed using the Vishap Oberon Compiler and then GCC. The compiled console programs can be run in the built-in terminal emulator.
- Gnash is a GNU Flash movie player. Flash is an animation file format pioneered by Macromedia which continues to be supported by their successor company, Adobe. Flash has been extended to include audio and video content, and programs written in ActionScript, an ECMAScript-compatible language. Gnash is based on GameSWF, and supports most SWF v7 features and some SWF v8 and v9. Features:
- Runs as a standalone application - Gnash can run standalone to play flash movies.
- IceCat plugin - Gnash can also run as a plugin from within IceCat.
- SWF v7 compliant - Gnash can play many current flash movies.
- XML Message server - Gnash also supports an XML based message system as is documented in the Flash Format specification.
- High Quality Output - Gnash uses OpenGL for rendering the graphics.
- GNU Radio is a software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in research, industry, academia, government, and hobbyist environments to support both wireless communications research and real-world radio systems.
- GNU Guile-SDL is a set of bindings to the Simple DirectMedia Layer (SDL). With them, Guile programmers can have easy access to graphics, sound and device input (keyboards, joysticks, mice, etc.). Most of the SDL functions are wrapped, with the exception of a few functions that are too C-centric. The SDL threads and audio functions are not included. However audio programming can be done with the module SDL_mixer… Also included is SDL_gfx 2.0.22 and bindings for it. NB. the guile-sdl2 project has been launched to create pure Scheme bindings for SDL2.
- Programs for Information Topology Data Analysis Information Topology is a program written in Python (compatible with Python 3.4.x), with a graphic interface built using TKinter , plots drawn using Matplotlib , calculations made using NumPy , and scaffold representations drawn using NetworkX . It computes all the results on information presented in the study , that is all the usual information functions: entropy, joint entropy between k random variables (Hk), mutual informations between k random variables (Ik), conditional entropies and mutual informations and provides their cohomological (and homotopy) visualisation in the form of information landscapes and information paths together with an approximation of the minimum information energy complex . It is applicable on any set of empirical data that is data with several trials-repetitions-essays (parameter m), and also allows to compute the undersampling regime, the degree k above which the sample size m is to small to provide good estimations of the information functions . The computational exploration is restricted to the simplicial sublattice of random variable (all the subsets of k=n random variables) and has hence a complexity in O(2^n). In this simplicial setting we can exhaustively estimate information functions on the simplicial information structure, that is joint-entropy Hk and mutual-informations Ik at all degrees k=<n and for every k-tuple, with a standard commercial personal computer (a laptop with processor Intel Core i7-4910MQ CPU @ 2.90GHz * 8) up to k=n=21 in reasonable time (about 3 hours). Using the expression of joint-entropy and the probability obtained using equation and marginalization , it is possible to compute the joint-entropy and marginal entropy of all the variables. The alternated expression of n-mutual information given by equation then allows a direct evaluation of all of these quantities. The definitions, formulas and theorems are sufficient to obtain the algorithm . We will further develop a refined interface (help welcome) but for the moment it works like this, and requires minimum Python use knowledge.

- Image viewer for X11/Wayland
- The Official Hamster Republic Role Playing Game Construction Engine (OHRRPGCE, usually abbreviated to OHR) is a cross-platform (GNU/Linux, Windows, Mac, BSD, Android) easy to use game creation engine for 2D role-playing games (RPGs) similar to the classic Final Fantasy. No programming is required to create a game, though there is a custom scripting language called HamsterSpeak which has been used to create numerous non-RPG games including side-scrollers/platformers, rogue-likes, arcade games, puzzle games and more. The OHRRPGCE has been in active development and had an active community for over 20 years, with over 1600 games available for download, plus a few commercial ones. Unlike other game engines, backwards compatibility is maintained with all previous versions ever released. It has been free software since 2005, whereupon it was ported from QuickBASIC (and MS DOS) to FreeBASIC and given new life. The community is centred around the Slime Salad forums and gamelist.
- A game engine providing a Lua API to enable developers to create games easily and with few restrictions.
