Swedish agency North Kingdom asks consumers to capture and kill "buffer" monsters for Vodafone Germany. Here's how it works: The app shows you where buffer monsters -- those nasty little things that slow everything down -- are located. Once you're there, you use the augmented reality function on the app to find them and capture them. When your holding cell is full, march on over to a Vodafone store and empty it. In exchange, you get points and badges. The best buffer busters could win three lifetime plans from the phone company.
The idea reinforces Vodafone's status as the fastest network in Germany.
