I really like the following image because it has to do with books. Also, it reminds me of the optical illusions popularized by Giuseppe Arcimboldo, Renaissance painter and party planner for emperors. Like the image below, he created portraits of people using composites of things or animals. It’s fascinating to look at closely, and equally so to step further away and discover the larger picture.
