Kasia Jackowska's *Drawing Mathematics* series takes an unusually adorable approach to illustrating mathematical concepts. The Pythagorean Theorem and Sierpinski triangles are conveyed through drawings of elephants, snakes, and deer.

Jackowska created this series for a brochure published by the Department of Mathematics of the University of Warsaw. You can see the rest at her website.
