The chapter discusses the innovative use of Penrose tiling in the atrium floor of the Molecular and Chemical Sciences Building at the University of Western Australia in Perth. Penrose tiling, discovered by mathematician Roger Penrose, is a "gap-free" tiling based on five-fold symmetry, featuring two types of tiles: the 'kite' and the 'dart'. This tiling pattern, developed by architect Gus Ferguson, creates a complex and aesthetically pleasing floor design. The pattern, composed of fat and thin rhombuses, forms a unique spider's web of lines that challenges the viewer's perception and cognitive abilities. Despite the aperiodic nature of the tiling, the pattern evokes a sense of spatial coherence and coherences, such as five-pointed stars and bilaterally symmetrical polyhedra. The lack of shading or coloring in the tiles allows visitors to engage in a spatial game, enhancing the overall experience and making the pattern both visually and intellectually engaging.The chapter discusses the innovative use of Penrose tiling in the atrium floor of the Molecular and Chemical Sciences Building at the University of Western Australia in Perth.
