The Tafla Geometric Mirror Collection squares off the balloon-like design with exacting linear proportions. Engineering innovator Oskar Zieta extends the innovative FIDU (short for free inner-pressure deformation) beyond his original crumpled furniture to wall hangings that are nothing short of works of art. While they suggest silvery mylar balloons, each piece is made from thin welded sheets of steel. They are inflated with high-pressure air, making each one of a kind.
