-Converts an image to triangles using Delaunay tessellation, or to
-polygons using Voronoi tesselation, and animates the result at
-various depths.
-
-More polygons are allocated to visually complex parts of the image.
-This is accomplished by first computing the first derivative of the
-image: the distance between each pixel and its neighbors (which is
-essentially edge detection or embossing). Then the Delaunay or
-Voronoi control points are chosen by selecting those pixels whose
-distance value is above a certain threshold: those are the pixels that
-have the largest change in color/brightness.
