## A Basic Particle System

Particle Systems are physics models that model small particles. Long ago those systems have been introduced to game engines and are the foundation of creating a realistic looking environment. They are great to, for example, model explosions, vapor trails and general lights in a game.

## Intersection of Line Segments

In this tutorial we improve the collision detection "algorithm" of the previous tutorials by restating the problem as a line or segment intersection problem.

## Basic Ad Hoc Collision Response

In this tutorial the equation of reflection off of any hypersurface, i.e. off a line in 2D and off a plane in 3D, is derived from the known observation that the angle of incidence equals the angle of reflection.

## Stécker vum Himmel (Beta Version)

The beta version of "Stécker vum Himmel", a Tetris-clone powered by the bell0bytes game engine, was just released.

## Et sic incipit!

The faithful black Eurasian dog was lying on its side, on the grass, at the outskirts of the garden, soothed by the sound of the water slowly flowing down the nearby stream.

## Episode I - Rebel Yell - Mara Sara

With the fall of its sister planet, Chau Sara, the inhabitants of Mar Sara were scared to death. And rightly so. Rebel Yell follows the newly elected magistrate of Mar Sara on his mission to bring order and justice to his fellow Mar Sarians.

## The Battle of Chau Sara

At Chau Sara, humankind made first contact with two alien races: the Zerg and the Protoss. War was imminent!
