A completely new version of this plugin is available and it allows to use the latest Polymer components: <a href="https://wordpress.org/plugins/wp-polymer/" rel="ugc">WP Polymer</a>
This plugin allows to add Polymer elements (v0.5) to your posts and pages, the same components used in Android Lollipop. You can use the HTML editor with the Polymer tags directly or the shortcode [poly] for all the elements. The correct HTML libraries will be loaded automatically. 
Polymer website: http://www.polymer-project.org/
Notice: Polymer is still in developer preview, some constructs may change in future. A modern browser is required to run Polymer web apps.

Notes
<ul>
<li>code blocks allows to create elements and import them directly from the Polymer box in posts / pages. They allows also to load JSON data, see FAQ for an example</li>
<li>autop option: the autop() WordPress function adds p and br tags to the contents when a newline is found, but this can break the Polymer tags. This option allows to enable/disable autop() in posts / pages (plugin default: no autop)</li>
<li>template override option: if this option is enabled this plugin will load a special template which provides only the required components to run a Polymer app. This is useful if you want a “fullscreen” Polymer app</li>
<li>to create RESTful apps try JSON REST API (WP API) plugin. See FAQ for an example</li>
</ul>
