Here is an idea that rocks: Students at the University of Karlsruhe have developed Rollit, a housing design where spaces serve different functions depending on how it is rolled. For example, you can roll between having a bed on the ceiling or a desk.
It gives new meaning to the word "mobile home".
According to Archdaily:
Roll It, a cool experimental house, resulted from the collaboration among different institutes within the University of Karlsruhe. This cyclindrical design is a modular protype that provides flexible space within a minimum housing unit. Three different sections are dedicated to different functional needs: there's a bed and table in section, an exercise cylinder, and a kitchen with a sink.
