I wrote a small JavaScript a couple of years ago that grabbed a users (mine) most recent tweet and then parsed it out for display including links, date etc.
You can use a Twitter API wrapper, such as TweetJS.com which offers a limited set of the Twitter API's functionality, but does not require authentication. It's called like this;
TweetJs.ListTweetsOnUserTimeline("PetrucciMusic",
function (data) {
console.log(data);
});
