How to define your space?

Have you looked around your office, break room, conference room... What do your walls say about you, your office, your clients? Maybe it is time to spruce them up a bit. We can do this with many elements but a common practice is art work. But then what kind of art work, pass projects, company photos, mountains and scenery, local land marks, or just random flowers, old images, etc. Art work is sometimes a display of what you have accomplished or what your passionate about. What do your walls say? What do you want your walls to say?
