Did you stage some interesting titles in camera. Check Alan Kohler on ABC always good to watch what books he has in shot
The back drop was very interesting.
No books, but some Aboriginal art (I've acquired my mother's taste for it, although not yet the size of the collection). If we were doing it in my study (which I don't use for interviews because the lighting isn't good for TV) you could have a backdrop of folders of OA Board papers instead...
I should do an interview from my family/dining room with a backdrop of my wall of rogaining (and the occasional orientering) badges. Of course when I say family room, it's a family of bikes.
