Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

  I created a collection of small examples in Three.js to understand very quickly the purpose of some functions.
  You can visit the 'website' of the entire collection of pens here : http://mamboleoo.be/learnThree/

  You can also see the collection in CodePen

  Do not hesitate to comment if there is something wrong (I'm still learning)

  Thanks !
