Beard grows on interactive billboard

An interactive billboard set up by the South African shoe maker Bronx shows a man's beard growing based on the number of Facebook Likes. Users of the company's Facebook page are also encouraged to invite their Facebook friends to join in and thereby increase their chances of winning a pair of shoes. For every Like on the page, which also shows the number of users from different regions in the country, another strand of hair is added to the billboard in Cape Town.
