The Airbus A340 Glass Cockpit project is an intiative of the IRADIS foundation. It uses the glass cockpit library libGC developed for this project, which provides an open interface to the rest of the flight simulator and contains a framework designed for easy development of a glass cockpit.
Raydium is a game engine. It provides a set of functions which allows quick and flexible game creation. It features 3D captures, data repositories, in-game live video capture and playback, a themable GUI, networked physics, full Python bindings, and many other things. The main idea is to keep all this as simple as possible.
Particle Simulation is a playful simulation game which allows you to spray particles into the "air". The number of simulated particles is only limited by the speed of your computer. The particles don't interact with each other, but will bounce back from the ground and accelerate depending on a gravity constant. This constant can be changed (along with a number of other parameters) in the source code or via commandline parameters.
