Giving flat surfaces an "architectonic" treatment has long been a fascination with designers, and the newest line by Graham & Brown, Shape & Form, has accomplished this beautifully. The collection of wallpapers has a variety of "slights of hand" that provide textural interest, including geometric shapes, optical illusions and natural forms: each exploring the way light and shadow interact to affect perceptions. High gloss finishes, metallic sheens and tone-on-tone combinations lend extra heft to the interest these wall coverings contribute to a room. Shown, above, is Ephemeral in plum, and, below, Checker in white.
