Aliens and monsters 'invade' bus stop

LJ Rich reports on an advertising campaign that uses a camera and special effects to entertain commuters.

Commuters at a London bus stop have seen alien invasions, monsters from the sewers grabbing pedestrians and tigers running down the street as part of an elaborate advertising campaign.

The optical illusion was created by combining video footage from a camera mounted on the rear of the bus stop with prepared special effects.
