Just wanted to give a quick plug to ITP student Sinan Ascioglu’s new site: www.openprocessing.org — a community “flickr-like” site for Processing sketches. It’s terrific work and I’m hoping students in my courses will find it helpful for organizing portfolios of their work. I’m hoping to be able to help Sinan by figuring out a way to auto-generate thumbnails from uploaded Processing sketches. Seems to be the one missing piece (it’s a pain in the neck to generate those screenshots yourself). Any ideas? Post here in the comments.

Voronoi from shiffman on Vimeo.

Download QT version (better quality)

I installed a version of my new “Voronoi” project at the Jepson Center for the Arts and gave two workshops at local community centers about programming art with Processing. In the above video, the software continuously computes a Voronoi diagram colored according to pixels seen by a video camera. The tiles reshape themselves and move into place as the camera imagery changes.

Thanks to Harry Delorme and the Telfair Museum for organizing so many great events!

The library currently facilitates receiving single sample I/O packets in API mode, and returns an object that contains the analog values, digital values, sender’s 16-bit address and RSSI value. The next tasks will be to receive regular RX frames, issue AT commands and receive responses, issue TX frames and receive responses to those. We’d also like to support the XBee Series 2 radios, which have a similar API structure.

Here’s where you can download and learn about the library.

About a week or so before the ITP show, my Big Screens class had their own show at the IAC Building on their rather large video wall. I’m hoping we set the world record for largest Processing sketch ever. Some photos (video coming soon):

This, as far as I know, was the first public use of the Most Pixels Ever library, which admittedly needs quite a bit of work still.

Code snippets after the jump. . .

    Properties props = System.getProperties();

    props.put("mail.pop3.host", "pop.gmail.com");

    // These are security settings required for gmail
    // May need different code depending on the account
    props.put("mail.pop3.port", "995");
    props.put("mail.pop3.starttls.enable", "true");
    props.setProperty("mail.pop3.socketFactory.fallback", "false");
    props.setProperty("mail.pop3.socketFactory.class","javax.net.ssl.SSLSocketFactory");

    // Create authentication object
    Auth auth = new Auth();

    // Make a session
    Session session = Session.getDefaultInstance(props, auth);
    Store store = session.getStore("pop3");
    store.connect();

    // Get inbox
    Folder folder = store.getFolder("INBOX");
    folder.open(Folder.READ_ONLY);
    System.out.println(folder.getMessageCount() + " total messages.");

    // Get array of messages and display them
    Message message[] = folder.getMessages();
    for (int i=0; i < message.length; i++) {
      System.out.println("---------------------");
      System.out.println("Message # " + (i+1));
      System.out.println("From: " + message[i].getFrom()[0]);
      System.out.println("Subject: " + message[i].getSubject());
      System.out.println("Message:");
      String content = message[i].getContent().toString();
      System.out.println(content);
    }

    // Close the session
    folder.close(false);
    store.close();

and sending:

  // Create a session
  String host="smtp.gmail.com";
  Properties props=new Properties();

  // SMTP Session
  props.put("mail.transport.protocol", "smtp");
  props.put("mail.smtp.host", host);
  props.put("mail.smtp.port", "25");
  props.put("mail.smtp.auth", "true");
  // We need TTLS, which gmail requires
  props.put("mail.smtp.starttls.enable","true");

  // Create a session
  Session session = Session.getDefaultInstance(props, new Auth());

  try
  {
    // Make a new message
    MimeMessage message = new MimeMessage(session);

    // Who is this message from
    message.setFrom(new InternetAddress("name@gmail.com", "Name"));

    // Who is this message to (we could do fancier things like make a list or add CC's)
    message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("address@email.com", false));

    // Subject and body
    message.setSubject("Hello World!");
    message.setText("It's great to be here. . .");

    // We can do more here, set the date, the headers, etc.
    Transport.send(message);
    println("Mail sent!");
  }
  catch(Exception e)
  {
    e.printStackTrace();
  }

My class went to test their projects on the IAC video wall this week. The works in this video are by Young Cho, Hye Ki Min, and Ji-Sun Lee. The pieces in the photos below are by Daniel Liss and Lucia Jeesun Lee. All 15 projects will be on display in December. More to come!

Calling Processing again from shiffman on Vimeo.

Going to write this up and publish the code (in conjunction with my Big Screens course) in the next couple days.
