In 1968 Michael Webb of Archigram first showed the Suitaloon, a minimalist inflatable home that you carry on your back.
I thought it was brilliant and have been showing versions of tents that fold out of our clothing ever since, to much abuse in comments. Now it turns out that cartoonist/ visionary/ inventor Steven M. Johnson figured it out decades ago, calling it "a studio apartment with sleeves!" There is even a term for this kind of design- Hobotecture. Here are some of the other examples we have shown in TreeHugger:More Hobotecture, houses you carry on your back:
