Workspace

This is my new workspace.  The depth of the desk is perfect for me.  The picture itself is how I try to keep it.  It's not staged.  The keyboard sits in that position, and the mouse doesn't move much.  The lamp is wonderful.  The MacBook Pro can be setup on the left side of the desk easily without interfering with my work.  The walls are fairly bare, and I want to address this somehow.  Whatever goes up, I want it to fit the decor of the rest of the room.  I'd like to get something practical as well.  Or maybe a bit of both.
