Summary

A Giraffe, modified Voronoi Style
Print it in yellow and fill it with brown paper (or a brown colored napkin).

And please post a picture of your printed giraffe.

Here is a animation of this thing done in blender:

Do you know other models who would look cool in voronoi style?
Please leave me a comment!

EDIT 2013-09-13: I have added an other STL with the same Voronoi, but a bit thicker and hopefully easier to print.
EDIT 2013-09-18: I have added two more STL files. Both with support structure below the chin of the giraffe: One STL has only a small support structure, the other one is a bit thicker.
