The YouTube sensation PSY has made a district of Seoul in Korea world famous, for those who live in the Gangnam district life goes as normal and being Korea this means hi-tech.
On a trip to Gangnam, it will be soon clear that Gangnam Style comes in the form of eight two foot square marble QR codes. These have been built into the footpaths and a quick scan with a Smartphone will reveal exactly what Gangnam Style is!
