An Ember.js component for displaying a spinning loading indicator using spin.js.
See here for a demo.
bower install ember-spin.js
{{x-spinner lines=12 length=6 shadow=true color="#00F" width=20}}
Be sure to include both spin.js and x-spinner.js in your app.
You need to include x-spinner.js after you define your App = Ember.Application.create().
