SIMPLE_1 (SIMulation Program for Logistics Engin'g) is a discrete/continuous network-oriented simulation language with general-purpose programming language features. The Linux version of this software includes a project management system to automate integration of user-developed C/C++ code into SIMPLE_1 network models. A user's C/C++ code is interfaced with the SIMPLE_1 modeling language through information embedded in comments in the user's header file(s). SIMPLE_1 produces executable files with the help of the C++ compiler.
Motorsport is a project with a clear goal: to create the most realistic vehicle simulation possible. This includes cars and trucks, which can be driven using common input devices such as keyboards and steering wheels. It limits realism to what the hardware, and is intended for hardcore driving simulator fans. This means that it will try to have realistic physics, but not necessarily 'playable', 'easy', or 'fun' physics - these characteristics will depend on which vehicle is driven and on what a person is trying to drive it.
Multiplication Station will teach your child to add, subtract, and multiply. It is a multi-user application with a simple admin interface. All parameters are configurable, like grid size and the fonts and colors of number ranges. A countdown timer is used to keep the player's attention focused. A list of high scores is maintained.
Burr Tools is a set of programs for solving some kinds of puzzles, namely puzzles that are made out of square, cube-shaped, spherical, or triangular units, and whose solution also contains only pieces aligned along those grids. The program finds assemblies for the puzzle and animates how you have to assemble for some of them.
XiStrat (aka 'Extended Strategy') is in particular about turn-based, networked multiplayer, non-cooperative, zero-sum, abstract strategy board games (e.g., Chess, Go, Reversi variants, etc.) on 3D-visualized polyhedra and contains a server, client GUI, autoplayer engine, utilities, and documentation. Related recreational modern mathematics (single agent, cellular automata, graph/group/complexity/knot theory, discrete geometry, algebra, combinatorics, and mathematical physics) is also dealt with.
