Following Froyo, Gingerbread, Honeycomb, and other foods you shouldn't have at this hour in the day, Google's properly labeled its upcoming Android iteration. Introducing Ice Cream Sandwich, with an absolutely incredible new logo. (Surprise, surprise!) Google is calling it "the one OS that works everywhere" with new APIs to help with scalability — phones, tablets, and anything else in between. (We're assuming Google TV eventually, but there's no direct mention and the slide didn't show any TVs.) No pictures of the UI in action, but as you'd expect, Google is saying the new Honeycomb design elements will be coming to the phone with the update — "including the holographic user interface, more multitasking, the new launcher and richer widgets." On stage, we're watching 3D headtracking via the webcam, called Virtual Camera operator — it figures out who is speaking and focuses on the person. Alas, no word on release date. More pictures after the break!
