AKQA-San Francisco : Posey's Cast

When Buster Posey of the SF Giants was injured and put in a cast, AKQA decided to connect him with his fans. To commiserate with his early season finish, the shop put together a Twitter account, @PoseysCast and invited fans to tweet at him -- a virtual "signature" on the cast.

Then, five of the funniest tweets (and a haiku) were printed on an actual card and mailed to Buster.

Featured in the video is "uber fan" Maile Krauss, who reads out the tweets before dropping the card into a mailbox.
