I love this illustration by Claudia Pearson; it reminds me of our own bookshelf (that Peter MADE, thank you very mucho!). It's crammed to the gills with books going every which way, and is kind of a disaster, but it brings me so much joy to see our books all together. For example: Mine: Happy Kitty Bunny Pony. His: Manufacturing and Machine Tool Operations. Mine: Romantic vs. Screwball Comedy. His: Physics for Game Developers.
