Amazing stuff you never knew you needed! The Klutz Book of Inventions, a 200-page catalogue of never-before-seen contraptions that are equal parts brilliant, useful and ridiculous. None of them exists as an actual product, but in a funnier world, they would all be household essentials. This compendium was created over by an all-star team from Klutz and IDEO, the world's foremost product design firm. Each of the inventions was actually built in the legendary IDEO workshop before being photographed (usually in action) and described on its own page. Inventions include: a tricycle-lawnmower combo (puts wasted play energy to work), training wheels for high heels, scratch-n-sniff menus, mood collars for pets, and so much more. Isn't it time you upgraded your wish list?
