OK, the "everything is made of a million dots" rendering style is pretty neat. I don't think I've seen its kind before. I also like that it somehow ran perfectly on my phone.
IMO interactive in-world music peaked with Portal 2, the effort put into that was impressive.
It's an R Markdown notebook. I've been finding these to be a nice evolution on the literate programming concept. I also noticed the author has been responding in this thread but her account seems to have been immediately shadowbanned upon creation, seems to be a common issue recently.
Looks like the color is simply normalized so that one of the values is at maximum (255) and the others follow the shape of the spectrum. It's all very theoretical. If you're talking about what's physically possible, then you could just stop at "infinite temperature" instead of going into eye cones. Maybe if a body's temperature approaches infinity, you could get this color by standing at a sufficient distance, or wearing adequate sunglasses with uniform attenuation, or doing the correct safety squint like we do at the workshop.
Assuming this is for websites, what's the recommended way of handling cache busting with this kind of setup? The article has a slightly awkward paragraph that tells you to set long TTLs for everything and concludes with "tweak these settings", which kind of sounds like "draw the rest of the owl". Might be a good reason to use something that integrates all this (eg. Cloudflare Pages, since you're already using Cloudflare).
This is a fun exploration, though there's a lot of fuzzy usage of terms and missing stuff. Eg. the first 5 paragraphs are apparently trying to define timbre, yet the word appears nowhere. Same with harmonics, etc.
I think one of the most interesting things about pitch is that it's not well defined, it's a psychological phenomenon. If you could extract it from people's brains, you would likely get different values from different people. This is compounded by the fact that harmonics produced by real instruments are not exact ratios of each other, yet they affect the perceived pitch.
I like when people bring up Myers Briggs because it allows me quickly categorize them as "people who attach importance to personality types", and thereby make sweeping generalizations about them.
For fr/en, author Jean-Loup Chiflet has written a few books consisting entirely of what you're describing. The most famous is "Sky My Husband (dictionary of the running English)"
