iWorld is an Augmented Reality App that uses visual tracking to overlay iWorld-man on a physical piece of paper.
Just print out the target page from http://dev.junaio.com/publisherDownload/junaioMan.pdf and point your phone to it.
If you get too close, iWorld-man will go into attack mode. You can also poke him with your finger and drag him around.
