-Quick description:
-This script deforms an object (the pattern) along other paths (skeletons)...
-The first selected object is the pattern
-the last selected ones are the skeletons.
-
-Imagine a straight horizontal line L in the middle of the bounding box of the pattern.
-Consider the normal bundle of L: the collection of all the vertical lines meeting L.
-Consider this as the initial state of the plane; in particular, think of the pattern
-as painted on these lines.
-
-Now move and bend L to make it fit a skeleton, and see what happens to the normals:
-they move and rotate, deforming the pattern.

-Quick description:
-This script deforms an object (the pattern) along other paths (skeletons)...
-The first selected object is the pattern
-the last selected ones are the skeletons.
-
-Imagine a straight horizontal line L in the middle of the bounding box of the pattern.
-Consider the normal bundle of L: the collection of all the vertical lines meeting L.
-Consider this as the initial state of the plane; in particular, think of the pattern
-as painted on these lines.
-
-Now move and bend L to make it fit a skeleton, and see what happens to the normals:
-they move and rotate, deforming the pattern.
