Already tired of wallpaper? We just had this link sent to us (as have others), featuring Iconic Panels: carved relief laminate/wood panels that fit together to form a seamless wall of pattern. They can then be painted to achieve any effect you desire.
Manufactured by B&N industries in Burlingame, CA, the Iconics come in 11 different patterns. Our favorites? Broadcast above and Helvetica and Albert below. (Thanks, Kevin!)
