Maps are still the main technique to show geomorphological surfaces on different spatial scales. Step by step new technologies try to improve this approach. In this german article I wrote about a sandbox, which is monitored by a microsoft kinect camera. After some computation a beamer draws different heightlevels on the sand.
Obake, a developement of the MIT, tries to switch this approach and uses a surface which could be dragged and formed with hands. What do you think about. Would it be an alternative for classic maps?
