Polaroid's new line of photo-capturing gadgets includes glasses, GL20, that capture and display images and video on the lenses. The images also sent to a USB earpiece, as well as the GL10, a Bluetooth-enabled paperback-sized mobile printing unit. The GL10 is compatible with all Bluetooth-enabled mobile phones except the iPhone. The GL30 is a more traditional camera that takes, prints, and digitally saves pictures using the company’s "Zero ink" technology. Upcoming versions of the camera will also offer instant sharing of images to Twitter and Facebook.
