NINJA SPHERE: Much More Productive Than A Plain Ninja

Keeping an actual ninja in your house comes in handy just two times a year: when you’re cutting the Thanksgiving turkey, and scaring the crap out of your mother-in-law. But the Ninja Sphere ($199) is much more helpful around the house. Using data it collects from sensors and actuators, it learns about you and your environment, letting you keep tabs on the┬átemperature, lighting, energy usage, and other items around the house. It even lets you keep monitor pets and loved ones– so technically, no, it won’t work on your mother-in-law.
