A century ago, the Bauhaus school emphasized honesty of design and materials that reflect the true nature of objects and buildings, creating practical objects with linear and geometrical forms. Here Nicholas Fox Weber explores how the iPhone, with its effective design and its versatility, honors these deepest principles like few other modern objects. A close associate of Anni and Josef Albers—the last of the Bauhaus faculty—Weber offers a brilliant rumination on art and technology, extolling the iPhone as the essence of the Bauhaus principles of form following function.
