   naqsh.css — "Geometry, drawn by compass"

   One idea: Islamic star patterns are struck with a compass and a straight
   edge. This page performs that construction as you scroll — guide circles
   swing out, chords cross, and the star emerges from the intersections before
   the construction lines fade and leave the finished figure behind.
