The Happiness Counter, a smile-activated refrigerator, was developed at the University of Tokyo with the idea that smiling during everyday activities will make you happier. The refrigerator uses a camera that detects facial features, and will only open if you give it a smile. So next time you’re sad and want to eat your feelings, you’re refrigerator will keep its doors shut.
