Snap, the company formerly known as "Snapchat," on Saturday announced sunglasses that take videos through a built-in camera in the frame -- bringing to mind Google's controversial Glass product. Snap's Spectacles let users take 10-second videos by tapping a button on the top left-hand corner of the eyeframe. Users can tap on the record button to record another 10-second segment. They can record videos up to 30 seconds long in all. The videos can be stored locally or transmitted over WiFi or Bluetooth to Android and iOS devices.
