These are some scientific (computer science, physics, logic,...) articles and programs I have written. One of my main interests is visualization and other visual stuff and there are several programs from this field available for download.
This article gives a short overview of methods used for planning the
movements of abstract objects (could be a robot for instance) with several
degrees of freedom, followed by a complete discussion of a probabilistic
The algorithm described is well-suitable to many motion
planning problems in (mostly) static environments.
The article describes the algorithm in general terms and also
gives a discussion of implementation details and possible optimizations.
You can view the article as postscript or html!
The Probabilistic Roadmap Planner is a probability-based method for planning the movements of abstract objects with several degrees of freedom. The article describes the algorithm and provides a visualization in the form of a Java application and applet that is well-suited for use as a teaching material.

Superficially this is a colorful (see screenshot) variant of dominoes with weird tiles, a simple matching game to play during lunch breaks. But hidden behind this façade are the inference rules of natural deduction, so that every solved level represents a proof of a tautology. This program demonstrates that logical reasoning can be done without any language or symbols, relying purely on the brain's visual capabilities.

If you're interested in the scientific background, you can
read the article about the game.
If you have have a Java-enabled browser you can play the game online.
Alternatively you can download the game (with Java source code, licensed under the GPL) for offline use.
Evolve is a small Pascal program (source and DOS .EXE included) that simulates evolution in a group of simulated humans. It is a simple demonstration of the principle behind genetic algorithms.

A fantastic program to simulate the movement of particles under the influence
of Lennard Jones, gravity, Coulomb and quadratic potential. The program
was designed to be fun to use without making compromises in the physical

A cute and colorful program that simulates a turing machine. Just unzip and run. Like MDS this program is supposed to be fun even if you don't have the scientific background.
