This video shows how convenient it is when one thing can transform itself from one thing to another automatically.

Imagine the same thing one every scale from the bumps in the wallpaper, the furniture , the layout of the rooms to the overall structure of the house! Image a house that is infinitely and automatically adjustable! Need a Guest room for one day a month when grandma comes to town! just add a wall that day and use the space for something else the rest of the time.
