This set design project created for the Non Standard Architectures exhibition (2003-04), designed by Frédéric Migayrou at the Centre Pompidou, had to fulfill the requirements of a very precise program. It had to provide “a ribbon-like structure that served as a framework for demonstrating the historical genealogy underpinning the exhibition” and it had to “develop a mathematical pattern organizing the entire exhibition space with respect to a certain number of constraints.” EZCT transformed the grid composition of the Centre Pompidou into a mathematical pattern, a matrix, which it then manipulated in collaboration with the mathematician Yvonne Teissier, utilizing the Mathematica software application. Unlike 3D modeling programs that induce a “desire for form,” this application enables the user to describe the space in logico-mathematical terms by cross-referencing geometric, algebraic, symbolic and logical data. Their research led to a unitary pattern dividing the space into 12 zones of equal surface areas, optimizing the full range of spatial relations and circulation constraints. Several types of surfaces were tested over the course of the development process. In the end, a variation based on the Weierstrass function was selected.
