Today I got to meet Jake Weidmann (artist and Master Penman) and see his work at the Ohio Pen Show. His craftsmanship is amazing. Watch this (Youtube) video for glimpses of it.
I love his rendition of C. S. Lewis & the Untamed Lion.

Creators of the Apple Pencil and the ProCreate app consulted with Weidmann during their development, and made modifications based on his input. You may have seen his drawings in an Apple store, during a promotion.
