Pegboards are wonderful tools for organising all sorts of things. You can even use one to upgrade one wall of your office for a display and accessorising system you can easily switch up whenever you want.
Flickr user travisdodson doesn't have much on his wall (though in the back you can see a room full of gear neatly organised on a pegboard). Still, it's not hard to see how you could hang clipboards, photo frames, accessories for your many computers, and even plants on that versatile wall.
