The founders of Nerd Nite wanted illustrations to include in their popular science book How to Win Friends & Influence Fungi (St. Martin’s Press, 2024). The authors wanted entertaining and educational illustrations to accompany each of the stories featured. We worked with them to develop illustration concepts and execute 71 pen and ink illustrations that helped to tell these science stories. Topics included cephalopods, civil war amputations, the chemistry of fire, the Japanese art of useless inventions, camel spiders, the science of how to be hotter, mass extinction, and many others.
