If you're an art lover, what would be better than a tool that tells you what famous paintings are nearby when you're traveling? Art Authority for iPad ($9.99) is a popular app with over 50,000 paintings and sculptures from ancient times to today organized into 8 rooms. I love these sorts of resources that are coming to the iPad. And now the developer has added a location-aware feature that makes this app even better: The "Art Near Me" feature lets you check out what major works of art are near where you live, or see what there is to see while you're traveling. They've also enhanced other location-based features, and now include over 500 museums around the world.
