Google Glasses what? Sight is the next best thing. Sure this isn't real, but it may be some day.
Sight is a short futuristic film which was made by two students for their graduation project. It takes augmented reality to a whole new level by adding lenses over your actual eyes. These lenses make use of your surroundings and are all personally customised.
I love the idea of using a plain wall as a huge screen and the ability to have information constantly fed to you.
