Just pack up your home and go is the idea of the UMAMY Design Group's "Room of My Own" project.
The concept is to be able to fold walls and floors into one another, collapsing the furniture with it.
While the idea isn't exactly practical for entire spaces, we think this can be applied well to individual pieces of furniture. We like the thought of folding up a room, though. It would feel very much like living in a dollhouse. (via Cribcandy.)
