Imagine Spiderman going completely insane and losing control of his web shooters and then look at this crazy art installation by Viennese/Croatian design collective For Use/Numen. Using nothing but nearly 100 pounds of packaging tape, For Use/Numen transforms abandoned attics, galleries and stock exchange buildings into a spider's cocoon paradise. The coolest part about, of course, is that the installations invites visitors to sit and relax, asking them to partake in the experience.
