Passers-by on a London street were recently amazed to see a fleeting image of a pink tongue protruding from fruitily plump lips, seemingly suspended in mid-air. It was the famous logo for the Rolling Stones and was part of an experiment by tech start-up Lightvert. Its technology can produce images that appear to be 200m (656ft) high, but which only exist in the eye of the viewer for a fraction of a second. So could we be on the verge of seeing giant digital ads in our cities, similar to those featured in the seminal 1982 sci-fi film Blade Runner?
Lightvert certainly hopes so. Its tech, called Echo, works by employing a narrow - no more than 200mm - strip of reflective material fixed to the side of a building. A high-power projector mounted below or above the strip beams light off the reflector directly into the viewer's eye.

Buzz off Lightvert. Ads are bad enough.
I know I am not God, because every time I pray to Him, it's because I'm not perfect and thankful for what He's done.
