I'm so geeked out right now, I can't even tell you. Thank you human, for these lovely videos. I actually have never heard of any of this outside of fractals, and even then I just know of them. When I was in school I got a taste of discrete mathematics, and nothing alive can signal how little you know than getting even a taste of this stuff. It's absolutely brain tingling, even if some of that tingle is pain in my case. Hahaha! I love it though, and I thank you for the explanation and these. Off to watch!
