Brazilian agency Ginga Interactive did an amazing job making Teenage Mutant Ninja Turtles even cooler when they projected this intense scene directly onto a 25-story building in Sao Paulo. Created as promo for the upcoming Brazilian release of TMNT, this viral marketing scheme definitelty got some buzz flying; watch the amount of attention this gets from passerbys, and just think of all the added reach when you factor in camera phones, etc. And wow, just think of all the pranks you could play with a projector like that– I want one.
