//Tricolor v.2007 by Cynthia Lawson Jaramillo
//2012 version re-coded in Processing for the exhibition "CrossTalk: Speech Acts & Interference in Networked Art"

//This version would not have been possible without the PhP proxy code by Shawn Van Every downloaded from
// http://www.learningprocessing.com/tutorials/sandbox/

// and the following

// feedParser.pde
//
// Reads RSS and Atom feeds. Requires ROME 
// (https://rome.dev.java.net/)
// and JDOM (http://www.jdom.org/), just make
// a code folder and copy "jdom.jar" and "rome-*.jar"
// into it.
