For folks that know me as "the blue noise guy", I've put together a 50 minute video that talks about many of the things I've learned in my ~decade long dive into noise and related topics - up to and including our latest paper published days ago at I3D.
I hope you enjoy it!

I know you know what you're doing, but the left side image about "irrational" and "random" reminds me of the famous John Von Neumann quote that I really love:
"Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin."
@dougmerritt @demofox Nod. But "real" random isn't any fun.
@mbr @dougmerritt so true hehe
@demofox @dougmerritt To expand. With pseudo-random (or LDS) you have a set of known properties. And the fact you can repeat exactly the same sequences (or subset thereof) is of great value. Real random is a niche thing that's only has limited usefulness in "security" IMHO.
@mbr @demofox
Yes, correct, repeatability is extremely handy, and pseudo-random number generators are often a great thing to use -- except that your phrasing might give someone the idea that there's never any point in using true hardware randomness collection -- yet although niche, that sort of thing is very important in some niches.
(I just collected some hardware randomness within the last week, although really that's neither here nor there)
Randomness is a deep subject that very few technical people really understand. (Present company presumably excepted out of respect and politeness)
Anyway I hope it was clear that I wasn't criticizing, it was just an opportunity to share a quote that I really like.
@dougmerritt @mbr definitely clear. It's a great quote :)
@mbr @dougmerritt yeah. Having a deterministic mode is so great to verify you haven't broken anything as you change things :)
