(part of the exhibition Memory Palace) Let’s do a mnemonic exercise: let’s consider the cubic object as a space of memory, to the faces we will call map of the world and its continents, to the irregularity of its circular forms: black tulip, to the infinite line without beginning or end and to its inability of inversion: an impossibility. We are facing the Model for the impossible black tulip, a prototype that presents a convergent, connected, and continuous topological space, solved according to the principles of the Möbius Ribbon. This rotating sculpture executed by an infinite spiral line defines its shape by the presence of six circular sides in an isometric perspective.
