Nick Butcher (Developer Advocate at Google) recently published the source code for Plaid, an app meant to showcase material design on Android with playful animations, impeccable typography, and a simple, bold aesthetic. The code will provide useful examples for developers, but the app itself is worth keeping installed too - Plaid pulls stories from Designer News, Dribbble, and Product Hunt to serve up design news and inspiration, catered to your preferences.

Besides more standard material elements, the app has a few unique tricks. Specifically, the toolbar is behind the content rather than lying on top of it, making the scrolling action on the main grid a little more elegant.
