1) This course is made with words

• Powerful medium to share, graphicaly and semanticaly

text("word", 10, 30);

• Formating

textSize(12);
textStyle(NORMAL); // BOLD, ITALIC
texAlign(CENTER); //LEFT, RIGHTo
textWidth(32);

• Fonts

Can use a lot by default (all on your system), can load them online too. Ask us.

• randomText Array + Random index (float -> int)

• Moving text

    var part;
      
    function setup() {
      createCanvas(windowWidth-20, windowHeight-20);
        background(0);
      part = {};
      part.x = random(100000);
      part.y = random(100000);
    }

    function draw() {
      noStroke();
      fill(255,40);
      part.x+=0.01; part.y+=0.01;
      textFont("Verdana", 30);
      text("Here",  noise(part.x+10)*width,noise(part.y+10)*height);  
    }     

• Explosions
• Same than natural system. Just ... Start at the right position, and then apply random forces

2) Feed on the web

• Input - data from the web

• noise (perlin, for .. err ... drawing?)

• concatenation/split

• Manipulation possible on words LoadJSon/httpGet JSON
