Internet via overhead lighting

  > The lights will transmit data to specially equipped computers on desks below by flickering faster than the eye can see. Ultimately, the technique could ease wireless congestion by opening up new expressways for short-range communications. How much faster? My dad built a new type of ballast to reduce flickering because it absolutely drives dyslexics up the wall. Plug in a flicker-free light, and suddenly a lot of dyslexics can read without anywhere near as much trouble, people's headaches go away, and the light looks better, too - although that's my subjective opinion on the last point there. I'd rather run an extra cable and not get a migraine at work.
