The Sensu ($35) for the iPad is a cleverly designed stylus that incorporates both a brush and firm tip stylus into one device. The rubber stylus is exposed when the brush is closed. This stylus is great for sketching and writing or as a general navigation tool, at the other are the capacitive bristles of the artist brush. Check out the video below when using the app Paper by 53 with the Sensu Brush to create something amazing. Link
