Angry Birds is a smart phone app that has reached a kind of Pac-Man Fever or rather Angry Bird Fever for the age of the smart phone.
It came out of Finland in 2009, the nation that brought us Nokia Phones. The object of the game is hurl birds from a slingshot, which then crash into Green Piggy structures. The Piggies apparently stole the birds eggs and now the avian feathered friends want payback.
Extremely addictive, its like hurling paper balls or airplanes. A flag makes an appearance in the game, that of the Green Piggies. It is oddly modeled after the Finnish Flag.
