AugmenteDev. Absolutely cool toy - you print a few markers (small pieces of paper with patterns), place them around, and then you simply load a few 3D models onto your iPhone or iPad - these then appear at the locations of the markers, correctly scaled and rotated according to the markers. Very entertaining, even if it sounds banal at first. My to-do now is to convert my SL avatar into its own 3D model in various poses, and then have these as models on my iPhone to take photos from all sorts of places with my avatar in the picture. Oh, and the app is free for iOS and Android.
