Scientists in Isreal have created artificial spiderweb. Imagine anything (and everything) that contains thread or fiber, and note the improvement gained by using threads stronger than nylon or steel.

In a related (sorta) note, I once read a science fiction book where giant spiders were bred and used for construction purposes, spinning web the size of bridge cables. The very idea of riding a dump-truck sized arachnid like a mahout gave me nightmares for weeks.
