Pressing “snooze” in the morning a little too often? No worries — to the rescue is Gauri Nanda with her “Clocky.” How it works: If you hit “snooze,” the alarm clock jumps off your nightstand and lands on its wheels, beeping the whole time. Then it’s time to play hide-and-seek. The gadget rolls, bumps into things, backs up, and eventually stops. When the clock rings again, the sleepy owner has to walk around and find it to turn it off. Nanda invented the alarm clock for herself while she was studying design at MIT’s Media Lab. She says engineering helped her figure out which parts were needed and how they could be put together. She started her own design company, Nanda Home, and has sold more than 130,000 of the clocks in three years.
