The modern world can get messy. Fortunately, Swiss artist Ursus Wehrli is a man of obsessive order, as he demonstrates with eye-catching surprise in The Art of Clean Up. Already a bestseller in Germany, this compulsive title has sold more than 100,000 copies in less than a year, and the fastidiously arranged images have garnered blog love from NPR, Brain Pickings, swissmiss, and more. Tapping into the desire for organisation and the insanity of uber-order, Wehrli humorously categorizes everyday objects and situations by colour, size, and shape. He arranges alphabet soup into alphabetical order, sorts the night sky by star size, and aligns sunbathers' accoutrements - all captured in bright photographs sure to astonish even the pickiest of neat freaks.
