body: <p>I cannot get this koch snowflake drawing working recursively.</p>
  
  <p><strong>Recursive method</strong></p>
  
  <pre><code> public void koch(int n, double size) {
      if (n == 0) {
          t.forward(size);
      } else {
  
          koch(n - 1, size / 3);   // line 1
          stdTort.rotate(60);            // line 2
          koch(n - 1, size/3);     // line 3
          stdTort.rotate(120);           // line 4
          koch(n - 1, size/3);     // line 5
          stdTort.rotate(60);            // line 6
          koch(n - 1, size/3);     // line 7
      }
  }
  </code></pre>
  
  <p>Any help would be appreciated.</p>
