Help with creating a noise pattern

Could anyone suggest how to generate something like this


This is the source mentioned from the comments, it could be ported (with some effort):

I glanced at the code, not really sure what it’s doing or why its called noise. Maybe some kind of gaussian or perlin noise generation.

The display seems to add/blend some layers together. Something similar looking could be made with various waveforms overlapping, not true noise, but similar looking. Search for plasma effects. Something like this:

FastLED has a built-in perlin noise generator as well as supports the use of palettes, so that you can swap out the palette without having to change your HSV code generation. They’re both a thing of beauty.

As for plasma, that’s a lot of fun too, and is one of my goto web sites for that.
