Itau Bank, Latin America's biggest bank, and a World Cup sponsor, show the Brazilian national team how much the country cares about them, with "The Heart Ball." Developed by Africa and TUDO of the ABC Group, the ball "collected" heartbeats from fans from cities throughout Brazil, using a special app and sound amplifier. People had to place their hands on the ball, which would then capture their pulse. The heartbeats would then convert into a frequency that could be reproduced via a speaker inside the ball. The ball, which held the heartbeats of millions of fans, was delivered to the Brazilian National Football Team.
