You sure have heard of Instagram, but Instacube might be relatively new. Instacube is a purpose-built digital photo frame designed to pull images directly from your Instagram feed. The device is an Android-powered photo screen which includes speakers (to support Instagram video). Here is a video of how it works.
Future updates will imbue it with the ability to stream content from Facebook, Vine, Flickr and other services, too. The device will begin shipping out come April 5th.
