Could someone please explain to me in laymens terms, Cubemapping.. I mean if I cubemap a "Cube" and hang it in space... Drive up to it in my space ship... Will I see my ships reflection? I mean do I have to precalculate all of my cubemapped surfaces or are they real time??? There has got to be some good ways to make Objects look Reflective.

Both are possible...

If you render a runtime cubemap, why not. Do note that DX7 (non-shader) reflections are polygon based, meaning that they will look quite horrible (warpy) if you don't have enough dense mesh.

Now, Can you give me a small example of how to accomplish the realtime effect?

It would be greatly appreciated.
