You're probably familiar with Transformers from the TV show or movies, but have you ever heard of a house that transforms? This has got to be the coolest house ever!

Watch how efficient this Yo! Home prototype is as the room easily changes from one thing to another with the slide of a door or push of a button. It really is remarkable to see. Perhaps someday population densities in some places will be so high that space will be at a premium. In that case maybe many people will live in this type of home.
