Delaunay Images
Absolutely beautiful images based on something called Delaunay triangulations, which maximize the minimum angle of all the angles of the triangles in the triangulation; they tend to avoid skinny triangles.
This was created using a scripting plug-in for Illustrator by Jonathan Puckey– he calls his work Delaunay Rasters. Check them out, the faces are so great.
