NO ARCHIVES TPX IMAGES OF THE DAY Reuters PARIS - An art installation has created the optical illusion that the French capital's Eiffel Tower is perched precariously over a rocky ravine. The artwork, by an artist who uses the pseudonym JR, involved laying an image of a ravine, and the pillars that form the base of the Eiffel Tower, onto the floor of an esplanade that overlooks the tower.
