For your iPad sketching needs: Cosmonaut.
I love sketching. It’s fun to do it leisurely; it’s great to get ideas out fast. In fact, in the last Seattle CreativeMornings, Scott Berkun encouraged keeping an idea sketching/writing journal because it literally helps with creativity. That ‘s called Kinesthetic learning, which is to think while physically moving; and sketching fits that. Sketching is even a richer experience because the fingertips contain some of the densest areas of nerve endings on the body, are the richest source of tactile feedback. And now, there are all the possibilities of sketching on the iPad.
The creators of the Cosmonaut produced a device that is better than sketching with our fingertips (although we still use them as with any writing device, thus experiencing Kinesthetic), and it’s not so thin and pen-like (such as other available products), producing a more “sketch-y” experience, no pun intended.
I haven’t used the Cosmonaut yet, but really would love to. If anybody out there has used it, let us know what you think.
