Google has released a really informative video series this month called Cardboard on their Google Developers YouTube channel. The video above is called the Unity3D Guide and gives a basic overview of how to develop Cardboard applications using the Cardboard SDK and the Unity3D game engine.
I really hope they continue this series, and look forward to seeing more Google Cardboard tutorials in the future.
