Meet the Goji Smart Lock. Put simply, it's a lock that links to your mobile, sending you a photo of who's at your front door, allowing you to choose whether or not you let them in at the press of a button. Useful? To an extent, if you've got your hands full in the kitchen. Necessary? For those who can manage to down tools long enough to get to the door, maybe not so much.
We might not be living in a Jetsons-easy robot-powered future yet, but we're getting there. From talking barbecues to candy-making printers, we've rounded up some of the kookiest high-tech kitchen devices announced at this year's Las Vegas Consumer Electronics Show. Hey, some of them might even prove useful.
