KDDI has launched a new application in the app store which allows you to layer Twitter comments on the worke around you. Say for example you are on a beach in Mexico and you are wondering what sort of food you might find at any of the local restaurants. Point your phone at the scene ahead and voila, if anyone had been there ahead of you and left some tweets about thier experience they will be layered over the scene for you to see. Useful or lame? It will really depend on the twitter sources.

Personally I think the information will be more or less useless.
