My office is a cubicle too. I don't keep much stuff in it, since I try to stay away as much as possible. (I'm usually here only during my office hours or when I have to download a lot of articles - I get more accomplished when I'm home.)
I love working at home, but seldom get to. I'm here with my Dilbert cartoons tacked to the wall most of the time. Oh and I have a pink-haired troll doll in workout clothes sitting on top of the monitor to keep me straight.
