I never fail to be impressed/inspired by the work of Bertjan Pot. He rests around-about the same spot in my mind as Achille Castiglioni. Never one to be defeated, these masks arose out of an experiment originally intended for rugs. I'm also reading Bill Bryson's 'At Home' at the moment, which describes how the domestic environments in which we live have evolved. Both seems to attest to the idea that some of the best ideas are born out of happy accidents.
