Augmented reality sandbox using a kinect

Want to make all your 5 year old son’s friends jealous? What if he told them he could make REAL volcanoes in his sandbox? Will this be the future of sandboxes, digitally enhanced with augmented reality?
It’s not actually that hard to set up! The system consists of a good computer running Linux, a Kinect, a projector, a sandbox, and sand. And that’s it! The University of California (UC Davis) has setup a few of these systems now to teach children about geography, which is a really cool demonstration of both 3D scanning and projection mapping. As you can see in the animated gif above, the Kinect can track the topography of the sand, and then project its “reality” onto it. In this case, a mini volcano.
