I thought I'd note that one of my favorite pages on the web pertains to exploring Sierpinski triangles [0] "The sierpinski triangle page to end most sierpinski triangle pages ™" [0]:http://www.oftenpaper.net/sierpinski.htm

My favourite Sierpinski triangle page: http://www.oftenpaper.net/sierpinski.htm It shows many ways of constructing one, including links to Pascal's triangle.

Holy mother, this person is cool and this person's website is cool, too: http://www.oftenpaper.net/ (it even has an article on Arc coroutines, ha!)

Ah, this reminds me — for a very long time there was a page called “The Sierpinski Triangle Page to End Most Sierpinski Triangle Pages” - which was a stunning tour de force, it seemingly went forever, covering every possible way to create, consider, discover, unveil or rediscover the Sierpinski triangle (and its many, many variants) It was here: https://www.oftenpaper.net/sierpinski.htm Recently - in an internet mystery to end most internet mysteries - the page has gone off line. I don’t know how to contact the author to provide assistance, care, anything that is needed. There are copies in the archive.org - though I’m not sure the embedded code demo will work there. https://web.archive.org/web/20230317130700/https://www.oftenpaper.net/…

Yes, old school web! A few of the others I like: https://faculty.evansville.edu/ck6/tcenters/ ; http://paulbourke.net/ ; https://pomax.github.io/bezierinfo/ ; https://www.fieggen.com/shoelace/ ; https://www.wood-database.com/ ; http://www.oftenpaper.net/sierpinski.htm ; https://www.animatedknots.com/ . There are lots more out there but social media favors new content rather than timeless content. I want to see more pages like that so, following “Be the change that you wish to see in the world”, I am writing informational pages.

One of the coolest parts of the article is at the very end when he algorithmically constructs music with the sierpinski triangle. http://www.oftenpaper.net/img/sierzrp1.mp3

What you are getting at here is the fact that Mathematica is a symbolic language through-and-through. In my webpage here: http://www.oftenpaper.net/sierpinski.htm I try to give passing mentions to how the Mathematica language and its infrastructure make various things easier. As a programming language geek, I haven't found a language more powerful than Mathematica, and that's before considering the infrastructure it comes with.

Uh, wow, I think they earned that claim. There's so much in here, they even have a cow which fires lasers being dropped from a space shuttle. http://www.oftenpaper.net/img/understandingtheriemannsphere.gif seriously going to have to look more closely at this some time, it's fascinating in a "look what you can do with math/programming/mathematica" kind of way.
