Google and other big-name investors have funneled more than half a billion dollars into a relatively unknown startup, whose wearable tech could have applications in video games. While details about Magic Leap are pretty thin on the ground, this mysterious company today said that it has secured $542 million in a funding round led by Google. The wearable tech is said to merge physical and digital worlds, reports TechCrunch, although the company is keeping rather secretive about how it works, and what it can achieve. The company is at least keen to stress that it will be a "lightweight wearable," and will connect up to your smartphone to produce realistic 3D images and models that appear to be part of the real world around you. There's no word yet on when the tech's big reveal will occur, but it's clear from this sizeable funding round that Google is rather taken by it.
