Geodesic Dome out of Cardboard

Need shelter quick? I may need this myself someday.

From Here:

Build a Geodesic Dome out of Cardboard
These domes have served as an effective shelter against wind, extreme heat
and, once painted, rainfall. The largest of the three domes in the picture
opposite measures approximately 12' 7" in diameter and is about 6' 3" high
at its center. We recommend building the largest one. All the measurements throughout this web site relate to the largest size.
They are fairly inexpensive to build as recycled cardboard is the main
component and, if water-based paint is used, can be burned. The domes are
strong enough to attach decorative pieces and lighting components to the
inside. Assembly time, on site, is 3 to 4 hours for 3 people constructing
one dome with the appropriate tools.
