This is a cool idea! Minecraft Reality is an augmented reality app through which you can upload your Minecraft creations and then place them and view them in the real world through your iPhone’s camera. More than that, you can dump your models in public places where other users might bump into them and admire your work.
The app was created by AR developers 13th Lab, with the blessing of Mojang. It’s on sale on the App store for $1.99, but if you are going to pick it up be aware: It doesn’t support full functionality for anything but the latest iPhone, and won’t run at all on anything before the iPhone 4. So if you do have the latest iPhone, pick up the app and tell us where you leave all your creations so we can all go check them out!
