This is a giant-ass spider web made entirely out of packing tape. Like, nothing else. No glue, no popsicle sticks, no rubber bands, just packing tape.

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.

At the last installation inside Odeon (above), a former stock exchange building in Vienna, the group used nearly 117,000 feet and 100 pounds of tape.

Oh man, just imagine: you're climbing around in there, laughing and pretending you're a trapped fly, when all of sudden -- REEK! REEK! REEK! -- that little freak from the Exorcist comes spider-walking down the web towards you. I don't know about you, but I'd totally shit myself have no choice but to exercise her ass. ON THE ELLIPTICAL, DEMON-SPAWN!

Hit the jump for several more pictures and a worthwhile time-lapse of the web being constructed.
