It's pretty hard to get a reaction out of London commuters; we're too busy burying our heads in a newspaper, scrolling through our phones or generally avoiding eye contact.

So Pepsi Max achieved something of a milestone this week as they made the capital's commuters gasp in astonishment at their surreal "augmented reality" bus stop installation.

The stunt, created at a New Oxford Street bus stop for one day only, aimed to "give commuters an unbelievable moment in their day" by projecting a series of incredible scenarios onto a digitally enhanced screen.

The construction of the screen gave onlookers the impression that they were looking through a pane of glass to the world outside, when really they were seeing a digital display.
