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.

Their image actually was chosen well. They poke their tongue out at all passers-by: "We blast our ads right into your face, and there's nothing you can do against it, ha ha!"
