Waiting for a bus to arrive can quickly become an excruciatingly dull experience, so Pepsi decided to bring some surprises to a London bus shelter to make waiting a bit more interesting. For its latest ad campaign, Pepsi Max used augmented reality to turn a bus shelter's wall into a fake window that appeared to show flying saucers, an attacking robot, and a loose tiger — among other unlikely subjects — making their way down the street. Pepsi doesn't say exactly what it used to make the illusion happen, but it appears to have relied primarily on a camera outside the shelter that let it capture people and vehicles on the street. By the looks of it, no one was fooled for long — but it certainly had plenty of people doing double takes.
