The first installment of Google's fancy Nexus One design series focused on the sound quality of the device, and on the overall design. Well, part two is here now, and this time, we get to watch while HTC project manager Tomasz Hasinki and Android software engineer Romain Guy give us the goods on the Nexus One's OLED display and the interactive, 3D framework. We're expecting a couple more videos in the series, so grab a very tiny bowl of popcorn (it's pretty short) and check out the video, which is after the break.
