AKQA and Skunk collaborate on this awesome World Cup site for Visa. The centerpiece is the "Samba of the World" portion, which collaborated with 32 individual directors from around the world and asked them to share their nation's love for the team. The result is a "Samba" from different regions, with separate films for each. Saman Kesh was creative advisor.
There are also a bunch of other features on the site, from one that lets you teleport yourselves into scenes from football matches (get a rubdown, or score a goal) using your webcam, or let ambassadors from each country take you to celebrations around the world.
Visa's attempt is the latest marketer push that focuses on country-specific efforts. Coke, for example, made 32 local anthems from its World Cup theme song, while ESPN created posters depicting each team.
