Open Door Networks has released Art Authority, a new application that allows users to view a comprehensive collection of artwork directly on the iPhone or iPod touch. Art Authority provides access to works from over 1000 major artists, organized by period from ancient times to contemporary, with a database of over 40,000 paintings and sculptures. Device-optimized images are stored on Open Door’s servers and downloaded on demand, conserving space on the iPhone and providing a catalog that can be updated as needed. The application also provides detailed captions for each image and in-depth information on the periods and artists. Users can zoom and rotate images, save images, or display a full-screen slideshow with their own background music. Art Authority is compatible with the iPhone and iPod touch using OS 3.0 and available on the App Store for $10. An iPad version is also being developed.
