The latest "Tidbits" reports that Google Earth has posted Hi-res images of paintings in Spain's Prado Museum.

"While the project isn't an acceptable substitute for seeing the
works in person, it is an exceptional upgrade to the sorts of reproductions to which we've become accustomed. The images of the 14 works, which include Velázquez's _Las Meninas_, Goya's _The Third of May 1808_, Hieronymus Bosch's _The Garden of Earthly Delights_,and Fra Angelico's Annunciation_, are 14,000 million pixels in size
- that's 1,400 times larger than an image that could be captured by a standard 10 megapixel camera! The extreme resolution enables viewers to see not only every stroke of paint, but even the weave of the canvas and cracks in the varnish."

This is an amazing accomplishment and should eventually make the world's great artworks readily accessible.

Open Google Earth,enter "Museo Nacional del Prado, Madrid" as the destination, and follow instructions.
