Nth Screen is for capturing videos on multiple phones at the same time, and making mosaics. Hold up your camera phones at a concert, a wedding, a party, at any other social occasion or in any crowd. When anyone presses Record, they all record together. Upload your videos and make a synchronized mosaic in the web. Share.
Nth Screen works over the internet. You don't have to be in the same place. Why not record whatever you and your friends are up to at, say, 5pm GMT, wherever you happen to be?
