Part 2 of the Nexus One video series is up on YouTube. As a quick recap, these videos are created by Google to tell you how the Nexus One was developed. While in the first part they focused on sound and the concept, the second part focuses on the 3.7-inch AMOLED display and 3D interface. So grab yourself some popcorn (small is perfect) and watch the video after the break. [Via Google Nexus One YouTube Channel]
