Google Earth, the Prado and Tiepolo

Spain's Prado Museum has teamed up with Google Earth in a unique project that allows art enthusiasts to zoom in on the gallery's main works from anywhere in the world, and even detect details not immediately discernible to the human eye.The initiative, the first of its kind in the world, involves 14 paintings which include Giambattista Tiepolo's Immacolata Concezione.
