There's been a bit of a buzz about the new app, Paper, released by Fifty Three in the past few days. If you haven't heard about it, Paper is a simple drawing app that aims to replicate the feel and experience of using a nice sketchbook. It strips away most of the Chrome that is part and parcel with the current spate of drawing applications on the iPad. It's a powerful idea: remove the UI, and you're free to experience the tools on their own terms, just as you would a pencil in real life. You're freed from the cognitive load of choosing the size of your brush, and are able to concentrate more on the act of creation.
