Many graphics packages and paint programs for OSX are able to make use of the pressure, stylus tilt, or rotation information generated by a tablet and modifying the brush size, shape, opacity, or color of strokes based on data received from the graphics tablet. The stylus and its interaction with the tablet allows a very natural way to create computer graphics, designs and illustrations on your Mac.
Mac graphics tablet apps and their stylus-based interface have the ability to detect pressure, tilt, velocity and other attributes.
