The nib of the pen is bipart. Varying the pressure creates a variable splay. On a multitouch surface, both contact points are sensed. The upshot is a tablet can be used to create fine calligraphy involving realtime variable linewidth. The nib can also be manually set to a fixed width, for that type of artistic penmanship.-- FlyingToaster, Oct 26 2016 Wacom http://www.wacom.co.../cintiq-companion-2If you want to do serious art on your tablet, you need one like this...

As I said, this can easily be done with software. I suspect you just need to buy a better tablet...-- neutrinos_shadow, Oct 26 2016 random, halfbakery
