Web

A web, also called a spider's web or cobweb, was a grid-like design created to trap things. Spiders created webs to catch prey, but the term was also applicable in relation to activities and shapes, as well as organisations or subjects that were widespread. Clark Goodman saw the World Wide Web as a sign of humanity's psychological debt to spiders. (AUDIO: Worldwide Web)
