Open Door Networks has released an app providing access to collections of artwork from over a thousand of the Western world's major artists. Art Authority includes high-resolution images of famous art, as well as information about periods and artists. Users can also organize images into slideshows, which can include music. Most data is stored online, which while slowing access also reduces hard drive consumption. The app is available as both a Mac and an iPhone title for $10; an iPad version is currently in development.
