title: How to create more than one canvas with p5?
body: <p>I want to try some things with stereoscopy in 3 dimensions and I need 2 canvas but I find nothing. </p>
  
  <p>I've tried to use <code>canvas1.background(200);</code></p>
  
  <pre><code>function setup() {
      let canvas1 = createCanvas(100, 100);
      canvas1.position(0,0);
  }
  function draw() {
  //for canvas 1
      background(100);
      rotateX(frameCount * 0.01);
      rotateZ(frameCount * 0.01);
      cone(30, 50);
  }
  function setup() {
      let canvas2 = createCanvas(100, 100);
      canvas2.position(100,0);
  }
  function draw() {
  //for canvas 2
      background(100);
      rotateX(frameCount * 0.01);
      rotateZ(frameCount * 0.02);
      cone(30, 50);
  }
  </code></pre>
