Sounds like a party
Mikes margarita has introduced an iphone application for their "classic margarita" drink. The app is essentially a Mariachi band starter kit. You can choose to play the horn, shake the maracas, or strum the guitar. This is a nice use of interactive digital brand promotion that reinforces the brand position. I can totally see this app catching on and being used at parties.
When a group of people get together you have a ready made party! Here are some screen caps of the applications and a link to download the app. Have fun!
