How can I create the animation like the new Path iPhone app?
<p>I am trying to find some sample code to create the animation when the "+" button is pressed in the new Path iPhone app. When it's pressed a menu swirls out showing all the different uibuttons and if you press the "X" button, it swirls back. </p>

<p>Does anyone know of any sample code which could do this?</p>
