In Zaraguza Digital we experimented a bit. Namely with Facebook cover photo feature and a webcam. After a few tweaks, our regular Facebook cover became a real-time Facebook cover. Zaraguza live cover was launched on July 30th 2012.
NOTE: A cover is the large photo at the top of your timeline right above your profile picture. Facebook found out that people have a better experience viewing yout timeline when they see a cover that is as unique as you are. So now, you can see us, LIVE :)
