Jorge Orta (Rosario, Argentina 1953) lives in Paris. Artist and architect, Jorge Orta has been working on large-scale ephemeral works since 1973. Protagonist of an urban and social poetic language, he has developed many new and alternative forms to communicate: using mail art, video installations and performance in the early 70's, to large scale projections in the 80's. Over the last 20 years he has devised a polysemic alphabet of signs and symbols which allow him to address very diverse publics, and more recently he has been exploring the symbol "Heart" to consolidate art, mythology and science. Jorge's light projection work took on its veritable dimension in 1992 when he projected giant mobile images inside the Pompidou Centre in Paris and when he embarked on a human experience to project his signs on Machu Picchu Mountain in Peru. Since, he has covered the facades of the Venetian palaces at the 1995 Venice Biennale, and more obsolete places such as Capadoccia in Turkey, Cuenca in Spain, Aso volcano in Japan, Chartres and Evry cathedrals and many more.
