I don't like the word phyllotaxis.

I understand it was inspired by https://en.wikipedia.org/wiki/Phyllotaxis, but arrangement on leaves serves the purpose of growth in a specific niche. The pattern arises because naturally leaves serve to capture light - see the images on wikipedia there. Phyllo means green. The LEDs used here do not really tap into any of that, and the name is also a misnomer. That's not good.

I disagree with sibling comments. You are correct to express the confounding implications of a word choice. And they have only detracted from the point you make.

Of course the design is cool and beautiful, but it is not the thing it is called here.

There is no worse form of bikeshedding than naming pedantry.
