Love 'em or hate 'em, vuvuzelas are going down as one of the most iconic images (and sounds) of 2010.
And now there's an app fo that. SF ad agency Pereira & O'Dell, who we listed in our 2009 Hot 20 Under 40 issue, is capturing the spirit of the 2010 World Cup with an iPhone app called the Pocket Vuvuzela. Download it to sound off at your local bar or seriously piss off your roommates. It comes in three languages (Portuguese, Spanish and English) and offers 32 Vuvuzelas wrapped in the flag of whatever country you feel like rooting for. Each time a ref makes a bad call (which has been a 'plenty) or someone scores a goal, you can blow, shake or press the horn to make it known. Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzz! (Okay stop now).
