The latest gimmick from Unilever-owned ice cream brand Wall's is to take a mini ice cream truck (specially designed to fit into elevators and corridors) into offices. DDB & Tribal Worldwide, Amsterdam created this film clearly designed for social sharing and office employees around the world can also nominate their own office for a surprise visit by the truck, or call for a desk order of ice cream at the Wall's Facebook page.

The idea reminds us of various stunts by Coke as part of its Share Happiness campaign, and Wall's also has its own campaign hashtag, #GoodbyeSerious, of which this is a part.
