LG isn't gonna let rival Samsung dominate the ridiculous smart refrigerator market. The company unveiled its own touchscreen fridge at CES on Wednesday with a bonus feature: Amazon Alexa integration, so you can do everything from stream music to place grocery orders with a simple voice command. LG's new WiFi-connected Smart InstaView door-in-door refrigerator runs on the company's webOS platform, which was originally developed for TVs. A 29-inch HD touchscreen display is embedded in the fridge's right door, allowing you to browse recipes, watch videos, write memos to family mamebers, and keep track of important calendar events like birthdays and anniversaries. The fridge's left panel is the InstaView part--knock twice and you can see what's inside without opening the door and letting cool air escape.

In an enormous grocery store in northern France, the lights above the aisles aren't all they seem to be. They look ordinary--more than a mile and a half of fixtures exuding bright light, folded into a grid overhead--but they're actually flickering faster than the human eye can see. The unique patterns each individual section of lighting emits are a 21st-century twist on Morse code, meant not for people, but for the cameras on their phones. If shoppers grant the store's app access to their smartphone's front-facing lens, the phone can watch for the lights and use the pulses to pinpoint its location. Doing so allows the app to plot the best routes for shopping lists, tracking people as they travel through the store.
