String is a new IOS application which is usable via the iPhone or iPad which creates augmented reality from a series of gorgeous printed designs by the String team themselves. It's hard to explain so it's best I just show you through a YouTube video I've found.
Think of the possibilities this could present if utlised with 3D Glasses. I hear Google is cracking on with this one but for now this is keeping me entertained. I think if this was placed in a magazine, billboard, train station, wherever, I think it would be an awesome sight for passers-by and a great opportunity for business to advertise themselves.
