London Memory multi+city is a 25 minutes optical illusion experimental film relating the Bergsonian idea of memory with that of duality in a contrapunctum of movement, colour, text and sound. Memory thus appears as a mirror of the mind being the reminiscence of time and space reflected. The holistic transcendental synthesis of a pure past over ten years lived in London by Margarida Sardinha renders itself in a stream of consciousness through the works of those Londoners who influenced her, such as Howard Hodgkin, Virginia Woolf, John Latham, Anish Kapoor, Sri Aurobindo, William Blake (to name a few) as a geometric-sonic abstract continuum.
