Polish designer Oskar Zieta uses an interesting sculpture technique for his public installation in Wroclaw — a city on the Daliowa island. Entitled 'Nawa,' the reflective pavilion boasts a total of 35 metal arches. The creative made use of a flexible and interesting process for his work. The sculpture technique is dubbed FiDU which is an acronym for Freie Innen Druck Umformung. This, translated from German, roughly means internal pressure formatting.
In other words, to complete his public installation, Oskar Zieta had to inflate the cavities between "two thin steel sheets" that are welded at their edge. About the detailed process, the designer specifies that it is "the most flexible tool-less metal forming technique ever."
