On February I was working with Polymer.js 0.5 and created a small project to test this awesome framework out. => https://api.fullstackweekly.com/web/polymer-dashboard-using-material-design/
After many learning mistakes, testing around and with the release of Polymer.js 1.0 I rewrote the project.
You can find the new project at https://github.com/bstavroulakis/polymer-dashboard and
a demo at http://demo.polymer-dashboard.com/pages/auth/auth.html
You can give it a swirl, test around and even fork, send commit requests and use it on your own projects as well.
