People like Kojima and Yoshimura have these on their work desk, you can too!
Not that I'm ashamed of my interests but my work office doesn't seem like the appropriate place for that kinda of things. It's a fairly serious environment.
That being said, I barely have anyone into my actual physical office so I could probably get away with one or two small things.
As a side note. Somehow, this little guy keeps kicking around our kitchen area.
