Hamsterball House

A spherical'ish¹ dwelling, all the lightweight amenities and furniture built in (and secured) on the inside wall. As the occupant walks from room to room the house tilts and rolls along a number of shallow ditches on the property. Make a left turn to go into the kitchen and the house rolls left too. The paths within the house match the complex ditch outside the house. The design is obligate polyouroborostic, so the house won't wander off the property.

Houses on small lots ride atop a bebearinged pedestal, without changing their ground position.

Larger, heavier, houses use a motor-driven internal ballast (central water tank, universal paddler), or gyroscope to assist.

¹ "ish" because only the portions that ride in the channels have to be spherical arcs while in motion²: the rest can deviate from the spherical shape as much as the ditch spacing allows.

² In order to keep floors level while the occupant is in the room, while not necessitating standing or sitting in the room's exact weight-distribution centre, the "sweet spot" is increased:

- The track arcs are spring steel which flatten out against the underside of the room's flat floor. This enables regenerative stop/start rolling, mitigating positive or negative momentum while walking into or out of a room, as well as keeping the floor level while the occupant is inside.

- In the larger active roll-management houses, friction plays a large part in keeping the floor level, while doorway sensors between rooms control the machinery.
