 Inigio's experiment on voronoi didn't stop there. In 2014 he wrote this nice article about what he call [voro-noise](http://www.iquilezles.org/www/articles/voronoise/voronoise.htm), and exploration between regular noise and voronoi. In his words:

 Another interesting property of waves is their ability to add up. Add the following lines to the previus example and pay atention how the frequencies and amplitudes change conform we add different waves.
