Simulation of water waves on the X Windows desktop. Windows and mouse are like ships on the sea. Each movement of these ends up in moving water waves. You can even have rain and/or storm stirring up the water.

Winboard 4.5 32-bit is a free Windows accessible Chess program that works automatically with the JAWS or the free NVDA screen reader. It is for the blind, low sighted or those who can not use a mouse. It provides vocal announcements of position changes and other selectable board conditions. Blind players also use a separate "tactile chess board". Winboard 4.5 has full keyboard access to move pieces and run menu items. Partial sighted players use high contrast mode and adjust board, piece, most font sizes and colors. Available languages are English, German, Spanish, Italian, Dutch and Russian. Games may be viewed, modified or saved in standard PGN format. Two Chess engines supply play and grand master strength move analysis. Connect to the Free Internet Chess Server (FICS) and play humans. Modify verbosity in screen reader configurations and in the Winboard "Sound" dialog under the "General" menu. Find all documentation in the "doc" folder under the Winboard directory of your C drive.

Sour*eforge.net has become inaccesible to me because of Cl*udflare. The latest version of skunks is on my site: https://matei.one/. 3D realistic driving (not racing) simulation with software rendering, based on Open Dynamics Engine (which is included in all *.tar.gz files so it doesn't have to be downloaded separately). 10 cars (all electric) and 16 tracks are available in version 5.1.0. Cars and tracks can be easily created and modified. Only SDL 1.2 or SDL 2 required besides standard C library. GNU/Linux and Wind0ws executables are available. If using GNU/Linux and SDL 2, it might be necessary to add -lpthread in the comp file, at line 2.

update: https://sourceforge.net/projects/newctruck3drally/ It's a 3D, physically realistic truck/car simulator, oriented to dirt tracks. This is subsancially kept as hystorical. The environment is a hilly terrain which can also be user-defined in the form of a Bitmap image file (where intensity of red component defines height). It's similar to the classic "Terep 2". Particular care for internal cam. Written in standard C. There's a Windows executable ready for use, but it's compilable and playable on all Linux, BSD, MacOSX systems. Official VIDEO presentation: http://www.youtube.com/watch?v=B74QvPGyBYM The physical simulation was written from 0 of course, so no external 'third-party' libraries are used; except GLUT+OpenGL for the graphical visualisation & good interactivity.

OpenUniverse is a fun, fast and free space simulator. It currently focusses on the Solar System and lets you visit all of its planets, major moons and a vast collection of smaller bodies in realtime 3D (using OpenGL).

Bad Camel Gaming is a collection of arcade games build on the Oasis Framework, the Bad Camel Gaming game framework.

This is a library to provide high-level control over force-feedback devices under Linux.

MASyV (Multi-Agent System Visualization) enables one to write agent-based models/cellular automata, eg. in C, visualize them in real time & capture to movie file with MASyVs GUI & message passing lib. Includes examples: Hello World, ants, viral infection

Nightsky is a very basic rendering of the stars in the sky for devices that aren't powerful enough to run Stellarium

A truck/car simulator,with realistic physics and oldstyle graphics: it displays pixels through the SDL graphics routines, or the X11 if using that version (has some issues:so use the SDL ver).While the 3D graphics is done by the program itself without external libraries.The environment is a hilly terrain:total freedom to drive around.A remake of the classic "Terep 2". Written in the C programming language: although the code is 30 pages long, it's simple. Trailer can be detouched pressming 'l' (minuscle ELL) so to drive a normal car. There's an OpenGL version too: see the CTruck3D _Open,and an ASCII-Art ver (Term_ CTruck3D). This is also a good dydactical software: code is easy to undersand,and drawing procedures and physics sim procedure are written from 0 so it's clearly understandable how a complete 3D game is done in C, starting from a blank page of any plain text editor.Only basic knowledge of C was used. VID: http://youtu.be/n_O-9EFW5zk Lagrande_Rally_3D is an evolution of this

Abrir a Caixa de Pandora significa compreender a questão da violência contra a mulher: suas determinações, suas raízes e suas consequências. Este serious game visa o enfrentamento do problema desta violência com foco na capacitação de profissionais de saúde. Considerando a violência como um problema social, fruto das desigualdades entre os gêneros, que representa uma violação aos direitos humanos femininos e se constitui num grave problema de saúde pública em todo mundo, os conceitos Gênero, Direitos Humanos e Saúde foram considerados como categorias principais do conteúdo pedagógico do serious game.
