Two interlinked tori create a 3D geometric object in the form of the number 8 – i.e., the sign of infinity. In myInterface of infinity series, the "face" is the actual face of the prominent mathematician Grigori Perelman, who has made an immense contribution to the geometric analysis of this object. I have used the tiled photographs of Perelman as a mapping wrapped around the surface of a 3D model of the infinity sign. In my project, the mathematician and his discoveries are merged into one, turning into a symbol of the infinite multidimensionality of the world. On the road to coming to grips with this multidimensionality, some outstanding individuals – geniuses – become guides for the rest of humanity.
