Re: Low FPS webcam - here's an approach that attempts to analyze coin tossing data from the _sound_ rather than the _video_, since sound is typically recorded at a much higher sampling rate (high enough to "hear" the spinning

A lot of replies here are missing the key idea behind Penrose: that the "substance" and "style" of any mathematical diagram are separable. For example, the "substance" of a diagram might be a collection of sets

I was inspired by this Rest of World post https://restofworld.org/2022/wordle-viral-turkish-japanese-t... to make a Hindi-language "Wordle" https://kach.github.io/shabdle/ just for fun.

Indeed, you can "learn" (by gradient descent) new parameters to this algorithm, to generate fractals in any target shape that you want! https://hardmath123.github.io/chaos-game-fractal-foliage.htm...

This reminds me of a small experiment I did with a friend, where we asked different people to independently write the HTML and CSS for a website (without communicating), and then put the HTML and CSS files together to see how well they work

You might also like this little book, "Computational Cooking," which is also, in a way, a meditation on the language of recipes. http://diyhpl.us/~bryan/papers2/CompCook.html

If you liked this, you might enjoy this little trick you can do with moiré patterns -- near the end of the post, I talk a little bit about the math behind the FFT connection. https://hardmath123.github.io/moire.html

You might also like the nearley playground, which lets you write a grammar in BNF and see all possible parsings of an input. You can even press a button and generate a random string that matches your grammar! https://omrelli.ug&#

Parsers in nearley.js [1] are written in a very readable EBNF-like DSL; then they get desugared down to a JS file that's a lot like your snippet. [1] https://github.com/kach/nearley

How cool! I was on the fence about whether or not to put up the source code— I'm _glad_ I did! Do you have a recommendation for a good reference that teaches about the various metrics for point-cloud distance? (I only used Chamfer dist
