Again, there are some new Irrlicht Engine related and very interesting projects and addons, which Irrlicht Engine users might find useful:

• ICE – IrrLicht Common Engine Framework: is an attempt to provide a framework for Irrlicht which will enhance rapid production of new projects. It has its own homepage.
• 2D Image and Sprite classes: Extremely useful library extending Irrlichts 2d capabilities. Can be downloaded with documentation, examples and a cool demo from its homepage.
• Irrlicht Particle Editor: It does not have its own homepage yet, but you can find any informations at this thread in the forum, there are some cool screenshots available, and you can download it from here.
• AVI Reader, created by rt. Take a look at the full code and the tutorial in this and this thread in the forum.
• Opengame.org, a member organization formed to promote the development and use of opensource 3D game software. On the opengame.org homepage you can find links to Irrlicht, and to its competition, like fly3d, neo and ogre. [Hello from Irrlicht to all, if you read this! ;)]

As always, I added links to the projects with homepage on the link page.
