Paper: the iPad sketchbook app from the brains of Courier (video)

Go figure -- Microsoft's Courier project lives again... as an exclusive app on Apple's iPad. FiftyThree, a company that features folks who previously worked on the aforesaid Courier initiative, has just put forth a monumental effort dubbed Paper. The app, which is available for free in the App Store, is a sophisticated sketchbook with a highly unique user interface that's seemingly designed with the budding artist in mind. Put simply, the company feels that this app is "where ideas begin," enabling users to capture mental light bulbs as sketches, diagrams, illustrations, notes or drawings before sharing them across the web.

Of course, "free" only gets you in the door; in-app purchases ($2 per brush, for example) keeps the creators in business, but it's unclear at this point if a paid edition will be offered for those who aren't much on cherry-picking what they do and don't want to pony up for. Not surprisingly, the app ships with native support for the new iPad's Retina display, and while fingers are welcome, a capacitive stylus is recommended. Eager to see more?
