In his latest picture book, The Art of Clean Up, Ursus Wehrli (an artist and comedian from Switzerland) meticulously rearranges things we encounter in everyday life—alphabet soup, a sandbox, a parking lot—according to color, size, and shape. The book is a follow-up to his previous Tidying Up Art books, where Wehrli used to “tidy up” famous artworks, such as Van Gogh’s room or Botticelli’s beach.
