Your Favorite AR or Augmented Reality App

Aug 7, 2012
A Few weeks ago me and a few friends were discussing apps on phones and we got onto the subject of augmented reality, in itself its quite a cool concept the apps i show my old auntie bel sure gets a half puzzled, half impressed look when i turn my phone to her and say "look ive turned you into a zombie"

what other AR apps do you guys know of and like, would be great to discover some new ones...there always such a novelty.
