Animation of a spider building an orb-web. Our spider begins by letting out a line and letting the wind carry it over the gap. This is the strand from which all the rest of the work is hung.. An actual spider trails the threads out loosely then pulls them tight, which is beyond the scope of this animation. That's why the thread doesn't always seem to be following the spider. But in fact, the spider is followign the same route a real spider would follow to make the part of the web that is being drawn at that time. Music is ripped from Neverwinter Nights.
