 Designing these structures involves intensive study of the combinatorial possibilities of sometimes quite curvilinear and fluidly shaped modules, creating a seamless, quasi-organic unity that can be either rounded and self-enclosed, or open and potentially infinite.The latter designs have proved useful and attractive for use in eye-catching architectural walls and screens, often featuring complex patterns of undulating, tissue-like webbing, with apertures which transmit and filter light, while generating delicate patterns of shadow.Writing in "Architecture Week" (August 4, 2004), Hauer explains that "Continuity and potential infinity have been at the very center of my sculpture from early on."
