Gallery: Weird and wonderful inventions from MIT's Media Lab

This is SandScape, a system developed by the Media Lab that allows people to reshape a computer-generated model of physical terrain by remodelling the bed of sand below it.?

?The system projects the computer-generated model onto the sand, with any changes to its surface replicated on the terrain onscreen.?

?For example, if a user raises the surface of the sand by pushing it into a pile, as seen here, the terrain in the computer-generated model will also rise.?

?The system is designed to provide a more intuitive way for computer users to interact with computer-generated models of the landscape around us.?
