A tour of Ouvroir, the virtual museum Chris Marker created in the online world Second Life with collaborator Max Moswitzer. Guided by Marker’s cat avatar, Guillaume-en-Égypte, visitors explore a 3D island of galleries, cinemas, and reading rooms inspired by Bioy Casares’s The Invention of Morel. The film documents this digital extension of Marker’s lifelong exploration of memory, art, and technology.
