Voronoi Tessellation

Tessellations/tiling are shapes that are arranged, without overlapping or gaps, and closely fit together. A common example of this is honeycomb hexagons as seen in figure 1.

Voronoi Tessellation is a mathematical technique that forms irregular tessellating. The simplest way to describe it that I understand is a Voronoi is a diagram where dots are placed on a plane and each dot has a colour. The colours move out from the centre and where two colours meet a boundary is placed. Thus an irregular tessellation pattern is formed. 

I did not understand the definitions on the internet until I found a Voronoi diagram generator which made a lot more sense, http://alexbeutel.com/webgl/voronoi.html

These irregular patterns are quite common in nature. They are found in many different places, for example, the venation of an insects wings and the spots on a giraffes fur. My abstract pattern visually resembles these Voronoi tessellations without the mathematical aspect.
