I have a Facebook app named "Rails Across Europe" I would like to add some multimedia to it. I want to play a short MP3 sound clip every time the player's train reaches a city. Each city will have it's own unique sound clip. Problem is, I have no idea how to do this from the Facebook API. I suspect it involves using the Flash player. Anyone know how this is done?
Perhaps this is what you're looking for? http://developers.facebook.com/docs/reference/fbml/mp3
