That would be great, because it would allow us to test more advanced stuff more easily, plus it will give us an idea of what the actual 3D driver will have to look like. It's definitely a direction I'd like to work in, especially when the semester break starts for real. I'm going to talk to Attila about getting the source into the Subversion repository. cu, Nicolai
