Paper is a new sketching app for the iPad:

The team spent months painstakingly figuring out how to emulate materials on a digital screen. For example, they had to understand how lead plays on the texture of paper, and how pen ink moves when you apply an artistic wrist flourish. Even more time was spent getting watercolor paint to bleed just right when you hold down your finger in place. Swipe your finger side to side quickly and the watercolor smudges like you’d expect it to. The point here is providing real tools to use every day while sketching, drawing, and creating — and to that extent FiftyThree has succeeded.

Looks fantastic.
