22 Vision: screens Our lives are increasingly dominated by screens. You're staring at one at the moment, when you could instead be staring at the view, or some art, or deep into your partner's beautiful eyes. There might even be someone staring at you right now, trying to attract your attention, whereas your mind is lost instead inside some swirling field of photons. Stick a screen in the corner of your living room and the family is transfixed by it. Switch on a screen in a pub and the conversation falters as eyes drift away. Be it gaming, computing, e-books or video, there'll soon be nothing quite so ubiquitous as the screen. Need some exercise? Take your eyeballs for a virtual Wii-jog. Waiting for a train? Why not watch an advert instead? Have a burning desire to know the cricket score while you're halfway round the world? There'll be a screen in your pocket can tell you. The shining light of the future will be the permanent screenglow illuminating your face. Best make sure you're plugged in, or fully recharged, else 2020's going to pass you by.
