Fluid Mechanics Valves

A library for rigid body simulation written in Scala. This project was created under the terms of a one-year project at school (Gymnase de Burier). Another program for testing and visualizing SiMS, Graphyx, is included.

Multiplayer online role playing game, based on original mechanics and setting, with a light client (runnable as a Java Applet) and persistent, highly customizable server.

JW Image Rotator (built with Adobe's Flash) enables you to show a couple of photos in sequence, with fluid transitions between them. It supports rotation of an RSS, XSPF or ASX playlists with JPG, GIF and PNG images, a wide range of flashvars (variables) for tweaking both behavior and appearance...
