New web site about Virtual Reality

Hi, some friends and I made a site about Virtual Reality in french. In the programmation topic, there are an OpenGL tutorial, a Java3D tutorial and a VRML tutorial.
We need your ideas about how to improve it, and to complete it. (it’s a school project !!!).

Please give me your impressions, ideas …
