Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

JavaScript

Babel includes JSX processing.

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.

			tl = new TimelineMax({repeat:-1, yoyo:true}), //we'll use a TimelineMax to schedule things. You can then have total control of playback. pause(), resume(), reverse(), whatever.
			i, dot;

		//we can remove the first point on the path because the position is already there and we want to draw the Bezier from there through the other points
		path.shift();

		for (i = 0; i < quantity; i++) {
