Explorers have the device in hand, early reviews have begun to flow in, and heck, you might have even seen Glass in person by now. Unless you've had a chance to slide the product on your head, however, a comprehensive tour of the near-final user interface has likely remained out of reach. Until now. The team at Project Glass has uploaded a brief (60-second) how-to video, giving you an opportunity to step behind the tiny display for a point-of-view preview. If you have a minute to spare, you can view the clip just after the break. Then, set aside some time for our comprehensive Explorer Edition review, complete with sample pictures, videos and plenty of first-hand impressions.
