Amazing campaign for Powerade done by Wunderman Buenos Aires which basically turned a microsite in to a live inforgraphic for each game using tweets during the Copa America Argentina 2011 (read: really really important championship). More details here at Digital Buzz. 

The microsite aggregated every tweet about every game, and compiled them into an interactive infographic style interface where you could explore the social interaction through every minute of the match. Very nice work. (thanks to José for sending it through!)
