// ITU Experimental Interaction, spring 2011. Mandatory Assignment #05. Jakob Fischer Jørgensen. Mail: jfis@itu.dk.
// Area: String Strings, File Strings, and Internet Strings.
// Theme: The lives of others.
// Requirements: Sketch must access something on the internet and use it; interactive; minimum two fonts.

// Basic sketch concept (refined since initial idea!):
// World map, which is mouseclickable. When clicked, will display temperature where clicked.
// Draws data from some kind of world weather website.
// When clicked, display temperature for 2-3 seconds with font A.
// Top of screen: "Click anywhere to display temperature" (or something similar) with font B.
// Based on the book's Example 18-5: Parsing Yahoo's XML weather feed manually
