Google Glass may be the coolest, most futuristic, most Minority Reportesque piece of technology we have seen come to life in the past few years. You may even have to be Tom Cruise to wear them.
This augmented reality device packs a ton of technology into a very tiny system. It houses a projector, display, phone, camera, battery and capabilities for GPS and internet! This was barely feasible in a smart phone just a few years ago, now the technology is small and light enough to wear as glasses. What a massive leap that is.
