So here is the complete source for my version of a hello world facebook app. It starts off from their footprints example that comes with the facebook client. This is a simple app where you vote for your pick of the 2008 president from the huge list of candidates at the moment! It then shows a tally of the top candidates and allows you to invite your friends.

You can see it in action at http://apps.facebook.com/americavotes

If you look at the source you will see it is pretty straight forward and I’ll try and post some snippets with details if necessary. A few pieces of code are copied from some public internet sources.
