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!

A slide showing how using the golden ratio low discrepancy sequence as a random number generator when giving players treasure in a video game, gives a histogram of treasure nearly matching the histogram described by the actual probabilities. With white noise, the actual histogram of treasure dropped is very different from the probabilities.
A slide showing how random numbers which are positively correlated on the screen give correlated resulting renders, uncorrelated random numbers give uncorrelated renders, and negative correlation random numbers give negatively correlated renders. Negatively correlated renders have the best perceptual quality, despite all three having the same actual error.

@EricLengyel I found the tube in my wife's office. My goodness, I have some new things to try and absorb now. Thanks Eric :)
I'll move them to the other side of the camera next time I record a video 😂

@demofox Heh, glad you found them! Was the tube damaged? It looks like the posters have gone through the wringer.

@EricLengyel no it was fine and the posters are good. I may have been eager to get them out hehe. They are great though, thanks a lot.
