-          Before we get into all the fancy animating its good to get a feel for how to make shapes in two.js. In order to do this we need to have an instance of two. This sets up a dom element that contains either an <code>svg</code> or <code>canvas</code> element to add to the webpage. The two object has a <code>scene</code> which holds all shapes as well as methods for creating shapes.

           Finally, let&apos;s add some motion to our shapes. So far the examples use <code>two.update();</code> to draw content to the screen. The instance of two.js has two particular methods for animation. The first is <code>two.play();</code> which calls <code>two.update();</code> at 60fps. This rate, however, will slowdown if there&apos;s too much content to render per frame.
