Remember the scene in Kubrick's 2001 where the astronaut walks around inside the circular room, going up and around the walls and "ceiling"? That was done, of course, by spinning the set and camera together, not by using an anti-gravity machine.

You could make a similar physics-defying movie with this cylindrical rolling house. Called "Roll-It", the round house was made in the University of Karlsruhe and is fashioned from OSB (Oriented Strand Board, a kind of fancy, high-tech plywood). One clear pathway runs around the internal circumference, allowing the inhabitant to move the house by walking or to get some exercise (clearly, stepping outside would be too much effort).

The central walkway also divides the home into two sections, one for lounging and working, the other for washing and other wet chores. On the dry side, you can use the space as a bed, easy-chair or a desk and chair depending on orientation. It's incredibly neat, if impractical.

On the other side, there is a toilet, a sink, and a cupboard for stashing utensils, along with a water-tank hidden within the wall. I probably don't have to explain the potential problems here.

As an experiment, and maybe even as a summer-house for the garden, I love the Roll It. As a real, practical abode it is clearly nonsensical, though, especially for somebody as lazy and messy as me. Imagine having to wash the dishes and tidy the whole house before going to bed. Actually, that's exactly what the Lady tries to make me do every night. She'd love this thing.
