In this Milan exhibition, the viewer can modify the spaces. The great artist-architect Gianni Pettena explains why

In questa mostra a Milano lo spettatore può modificare gli spazi. Il grande artista-architetto Gianni Pettena ci spiega perché

Gianni Pettena, a pioneer of the Italian Radical Architecture movement, has unveiled his immersive installation "Paper/Northern Lights" at the BiM urban regeneration project in Milan's Bicocca district. Originally conceived in 1971 as a pedagogical exercise at the Minneapolis College of Art and Design, the work consists of 49 kilometers of white paper strips hanging from the ceiling. Visitors are invited to physically interact with the installation by cutting through the paper, effectively reshaping the architectural environment and challenging traditional notions of fixed space and authorship.
