Well, for my own PC, it is located at one corner of my room and against a wall, so all I can see past it is white wall.
But for the Laptop I'm currently using, that is in another room, I can see quite some stuff past it.
I see a TV, a sound system, two big racks full of CDs which don't belong to me, some decorative pieces of ceramic figures, some decorative artificial plants, a single real small plant, a mirror to a little left, and a lot more if I look a little to the left or right.
Even with all the more stuff that I didn't mention here, it's still not messed up though.
It's very very clean, I must say, as the people who are here, including me, can't stand to see things messed up around the house.
