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.
