I'm no expert on visualistaions, just I love them...

As you seem to be experts (and I love G-Force) I dare ask you one question:
Is there any way to make a "natural"visualiser"? Or, even better, does any such thing exist already? I mean something using motives like flowing water, leaves, sun beams, blizzards, etc. - in the fairly realistic colours, but changing actively with the music, as this would be much more fun (and easier for the pc to count) than just playing a piece of music and a nature film together at the same time.
Great Thanks if you can help me
