Twitter in Processing: leading up to the ICM final

I am going to work with twitter for my final. This is a first attempt to deal with twitter data. I’m started by using the Twitter4j library and following the example on Jer Thorpe’s page. From there I needed to have more control of the words so I have moved the words into a class. The sketch below shows the words animating backwards in Z space. Due to complications with the processing for wordpress script, the words are not being displayed. Instead you see nulls where the words would be.

The code is below:

//Build an ArrayList to hold all of the words that we get from the imported tweets
ArrayList words = new ArrayList();

ArrayList wordsPicked = new ArrayList();

void setup() {
//Set the size of the stage, and the background to black.
size(640, 480, P3D);

ConfigurationBuilder cb = new ConfigurationBuilder();

//Make the twitter object and prepare the query
Twitter twitter = new TwitterFactory(;
Query query = new Query(“#Obama”);

//Try making the query request.
try {
QueryResult result =;
ArrayList tweets = (ArrayList) result.getTweets();

for (int i = 0; i < tweets.size(); i++) { Tweet t = (Tweet) tweets.get(i); String user = t.getFromUser(); String msg = t.getText(); Date d = t.getCreatedAt(); println("Tweet by " + user + " at " + d + ": " + msg); //Break the tweet into words String[] input = msg.split(" "); for (int j = 0; j < input.length; j++) { //Put each word into the words ArrayList words.add(input[j]); } }; } catch (TwitterException te) { println("Couldn't connect: " + te); }; } void draw() { //Draw background background(255); //Draw a word from the list of words that we've built int i = (frameCount % words.size()); String word = words.get(i); wordsPicked.add(new Word(word, random(width), random(height), 100, random(10, 30))); for (int w = 0; w < wordsPicked.size(); w++) { Word thisWord = (Word) wordsPicked.get(w); thisWord.display(); thisWord.update(); } } class Word { String word; float x, y, z, size; Word (String word_, float x_, float y_, float z_, float size_) { word = word_; x = x_; y = y_; z = z_; size = size_; } void display() { //Put it somewhere random on the stage, with a random size and colour fill(0, 0, 220, random(50, 150)); textSize(size); text(word, x, y, z); } void update() { z--; } void kill() { } }
