This video from Digg shows what it means to be a diehard soccer fan.
Carlos, the boy above, can't see or hear, but his friends and family created a system so he can still follow the World Cup.
They hand-made a board to resemble a soccer field and move their arms around it in real-time, mimicking the players'. That way, Carlos can feel what's happening in the game.
The process looks fairly complicated. But when Brazil scores a goal and his hands shoot up into the air — you know it works.
