Astounding cocoons made only of tape float in mid-air, capable supporting more than your average tree house.

Packing tape has gotten MacGyver out of many a jam, but he never managed to make an entire home out of the stuff. So he could probably learn something from Viennese/Croatian design collective For Use/Numen. The team uses nothing but packing tape to create huge, self-supporting cocoons that visitors could climb inside and explore.

Installed three times in the past year, the next deployment will be next week from June 9–13 at DMY Berlin's International Design Fair, which is now in its 8th year.
The installations, which look like the work of horrifyingly large arachnids, grew in scale and scope as the year progressed, first deployed inside a small Croatian gallery, then an abandoned attic during October’s Vienna Design Week.
