crystal space using and installing

I’ve tried installing cyrstal space, which succeded just now.
Now I want to use it, but I have no idea how it works. I’ve seen videos on youtube of people using it inside blender.
That’s my goal. So if anyone could tell me how to do that?
By the way, I’m using ubuntu 9.10

I think that was CrystalBlend. I haven’t heard anything from that project for a long time.

I think it’s crystal space:

The plugin’s name was blend2crystal. But, yeah, it’s defunct as far as I know.
