Vuvuzela makes a lot of noise for World Cup

For a little plastic horn, the vuvuzela sure stirs up a lot of passion. Some have called for banning it from the World Cup because, in great numbers, it creates deafening noise in packed stadiums. Right or wrong, it's become synonymous with soccer in South Africa. Pereira O'Dell wants to help fans toot their own vuvuzelas with a new iPhone app. The Pocket Vuvuzela lets you blare four different virtual vuvuzela sounds in support of your team by shaking the app or tapping an on-screen soccer ball.
