2way to 1way mechanism.
This is free for anyone to use, there is a super old preexisting patent for it, so it’s not mine, and is kind of a cool concept and easy to make.
So this is free for anyone to make or modify or optimize, no credit necessary and should be able to spread freely without patent troll level junk. Some things are more interesting just out there, no origin, just a thing.
Everything I make I put in the public domain, creative Commons zero or things like that, not everything needs to have an originator, and if I create something using patterns that others don’t use, but I didn’t invent the pattern, I just noticed it, I don’t think I should be considered to have invented it since the patterns always existed.
