Here's an idea:
The Turtle Shell: the only travel home for one you'll ever need! Carry it like a backpack, it opens up and/or down from the pack on your back like a turtle's shell to keep you shrouded from rain or sun, or to give you a nice rocking chair. Then unroll the bottom portion to release the soft waterproof mat that you can finally lie down on and have a nice, private sleep. Any ol' where.
I imagine this invention will unveil a whole new group of people calling themselves Turtles. Today, we call them Homeless.
Original illustrations, anyone? I know, no one reads this so I got to get to it myself or it'll never be invented someday.
Upon closer look, this is kind of a lot like the bear box.
