The original version was simply colored in unlikely colors, unless the mice had been put in a blender or roller-coaster for a few hours.
That version was created in TesselManiac! software ( www.tesselmaniac.com ) coded by Kevin Lee.
This version is in more likely colors, with fur and bits of anatomy collected from a photo of a real mouse and reshaped to fit where my tessellation doesn't correspond exactly to real mouse outlines.
