“Shapes for a perfect world”, works of art conceived as if they were aesthetic objects made in an imaginary world, once, after a global upheaval, utopia had already been reached. Thus, when there is nothing left to criticize, the creators could abandon themselves to the mere creation of beautiful forms. PSJM presents three constructivist reliefs produced with noble materials, such as mahogany wood or bronze and stainless steel. These wall sculptures are accompanied by pages from a fictitious diary in which the motivations and creative processes that lead to the creation of these beautiful forms are narrated. Once again, the work of PSJM brings together different disciplines: literature, sculpture, design and philosophical reflection.
