It took me some times, but I wanted to implement Fortune's algorithm to produce the Voronoï Diagram of a set of points in 2D, and I finally did. I originally thought of Voronoï diagram as a mathematical tool, but now I think that these diagrams can be beautiful by themselves. Take a look at the progression !
I can print diagrams in SVG files with quite a lot of features. The first gif above was an ugly beginning but now I can produce beautiful ones ! Let's add some colors. And well placed sites.
Geometry inspired diagrams
With an input image and a little work...
This is what I call Voronoi flowers :
This is what I call Voronoi Snowflakes :
