Hello Twitter
Task 3 of our mission is to create a Processing sketch that is able to change our current Twitter status. We will use the Java library Twitter4J from twitter4j.org, which encapsulates all the Twitter API calls into convenient Java objects to set the status. We will also use the Twitter developer website to create the necessary application keys and learn how to ask the user for permission to post a status update.
Prepare for Lift Off
To complete this and the following task of our current mission, you will need a Twitter account to post the tweets and access to the Twitter developer site. If you are already using Twitter, you are fulfilling the prerequisites for this task, as Twitter doesn't distinguish between normal and developer accounts; every Twitter user has the permission to create and register applications. If you have no Twitter account yet, go to twitter.com and register for one.
