I randomly came across this Creative Mornings/Vancouver talk by Jessica Hische who is an amazing letterer and illustrator. I’m a huge fan of her work, as most people who are familiar with it are.
Although she comes from a design background, in the first part of the talk she makes a great case about why designers should learn to code. Which, by the way, she she has done.
