I know next to nothing about soccer (a.k.a. football), but I gotta admit this Brazil vs. Ivory Coast match is more exciting than I thought it'd be. I can't say the same about the vuvuzelas though. In any case, to help neophytes like me, the New York Times graphics have helped a lot. Their most recent explains the mechanics of the free kick. They describe two approaches in the animated feature: the straight blast and the bend.
