For the movie release in Brazil, Ginga Interactive has created a series of marketing stunts both on and offline. Apart from creating and uniting various fan communities of the books and film, interactivity was brought to the underground metro system in São Paulo.
Interactive Posters were installed in various terminals of the metro system, with animated videos and content which bemused the diverse audience/passengers playing with the interface, and extra content sent via bluetooth to their cell phones (if they so wish to accept it).
Taking it to the streets! Touch screen navigation a la iPhone will come to dominate soon enough. If you never have to type, why interact via a keyboard and mouse?
