New digital paint brush for Touchscreen devices:

"Sensu was developed out of a desire to have an authentic brush to use with drawing and painting apps on iPhone and iPad. Of course, Sensu works well on other capacitive screens as well. The makers of Sensu learned tons from some of the best brush makers in the world–careful craftsmen who understand the subtle properties of hair taper, flexibility, and strength. They learned to build brushes that yield perfectly to different paint mediums and various surfaces."
