My friend and I are working on a project we call Rolly House. It is still early stage but we just got it rolling for the very first time! Eventually it will be something along the lines of what the students at the University of Karlsruhe made a year and some ago: http://rollit-09.de/ http://rollit-09.de/. The large metal wheel will get walls/floor/ceiling later on but it's a lot easier to manage it empty!
