This is a rework of the original jQuery plugin which can be found here: https://github.com/davatron5000/Lettering.js.
Grab it with Bower: bower install ng-Lettering.js
Include it in your AngularJS application
var myApp = angular.module( 'myApp', [ 'ngLettering' ] );
Apply it to your text
<span data-lettering="letters">This is a sentence</span>
<span data-lettering="words">This is a sentence</span>
<div data-lettering="lines">
This<br/>
is<br/>
a<br/>
sentence
</div>
