Coke-cola as official sponsor has gone all in.. WITH INTERACTIVE MINI-BOTTLES designed as flags of 18 WC counties, including the US. They are AWESOME.
Advertising Age posted a non-embedable video of them, so go take a look along with some interesting info on them bottles.
The bottles (which contain no actual soda) are also interactive. Through Facebook or iPhone and Android apps, fans can create special messages and avatars that can be delivered to other bottle owners. And markers on the bottles can activate augmented reality animations when they’re held up to camera smartphones.
