title: Creating string art from image
body: <p>I am relatively new to python. I would like to make some string-art portraits. I was watching this video which really intrigued me:</p>

  <p>I understand that to achieve this, I would first need to load the image, then do some edge-detection and then use some form of Delaunay triangulation but have no idea where to even start. </p>
  
  <p>I looked up some sample code for OpenCV and figured out how to do basic edge-detection. How do I then convert those to points? And then what sort of algorithm would I need to "fill in" the different gradients?</p>
  
  <p>I don't even know if this is the right approach to achieve this. Could someone please point me in the right direction and perhaps give me some sample code to get started? I would really appreciate it very much.</p>
