It did get maybe 90% there in a minute which is faster than a person would do it. Not a perfect tile, maybe take a few more interations. But not awful for cobbled together in a minute, and if your job is to come up with 50 or 100 different textures, still better than doing it by hand.

But as I noted, there are also already royalty free libraries for this stuff as well.

Not at all wrong, just showing what can be done with virtually zero effort and time.

I could most likely perfect it in a few minutes more, still a fraction of the time of doing it by hand. I'm not extending a proof of concept to win arguments on the Internet. 😉

But as I noted at the bottom of the comment, which apparently nobody bothered to read, there are ALREADY royalty free libraries for this kind of thing. So it also has to be faster than searching libraries that are already there.

Of course that action is it's own time sink as anyone who has gone looking for "the perfect font" can tell you.
