Gotcha. Well, I guess being an old guy and having never correlated someone's computer background to any kind of meaning other than they like that particular background, I guess I don't see anything into it. But hey, I work with a bunch of terminals all day long so there's not an opportunity to customize things there, and the one work machine that has a gui, I have just left the background as the default. That is a rule of mine, nothing personal on the work laptop.
