Recently, I’ve seen an issue that mentioned using a “special” random number generator from [XKCD-221](https://xkcd.com/221/). Unfortunately, I do not remember where it was. But, if you need such RNG, you can get it from here: [Xkcd221.jl](https://github.com/wildart/Xkcd221).
It’s Julia Random API fully conformant drop-in replacement to default RNG. It should work with most build-in numerical types, and functions from Random package.
Thanks to @rfourquet for his work on [JuliaRandom](https://github.com/JuliaRandom) ecosystem.

I think it fits very well in this package, it seems very stable. It should also be rather simple to implement.
? Thanks for implementing it!

Haha, that is even super useful (if you want to understand the API)!

Very nice feat, I was procrastinating on this issue Mosè mentioned and you made it! And you even managed to fully generalize the solution to any seed! 😃
