The
"Visual Insight" page of the American Mathematical Society (AMS) includes some wonderful images.
Take the one I've "borrowed" here, titled
{6,3,3} Honeycomb in Upper Half-Space, by
Roice Nelson. I encourage you to access
the article about this image on the AMS site.
I also encourage you to look at
Roice's blog, which has some more wonderful imagery based on mathematical concepts that I don't understand.
I detest having to say I don't understand the math (and I'm still angry over the way I was taught math in elementary school, which so profoundly bored me that I became viscerally aversive to later study of the discipline).
However, I am thankful that I don't have to understand it to enjoy this image. I simply realize that if I did understand the math, I probably would enjoy it even more.
I am delighted that mathematicians now have access to computers that can create such images, and that I have access to an Internet that allows me to see and share them.
