As a backer of Linda Liukas's Kickstarter for her book Hello Ruby, "a children’s book that teaches programming fundamentals through stories and kid-friendly activities," I have been getting updates on her progress. I recently received her 18th. This one details her process over the past year as she has built the book. It's fascinating and (not surprisingly) delightful. I really liked how much she learned from multiple iterations over a single drawing, and from her editor. I can't wait until the book is released.
