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.

@demofox i always knew, if there is a love letter talk to blue noise like that comes one day, it will be from you, and only you! Good job!

@mamoniem not enough people know about 1d blue noise textures, let alone spatiotemporal, and now the generalization to arbitrary spatial and temporal filters.
More people need to hop on the train :)
I think there is still a lot of work to do in the area too. Lots of useful discoveries left to be made.

@demofox i personally was not familiarized with the term till i saw you on twitter sharing about it frequently, hence it caught my attention 🤩 (results speaks to be fair) and i started building knowledge about it (integrating slowly into my personal work).
also, this is why i was expecting that at some point a deep talk about it wouldn't come from anyone but you😅
