Banknotes (money) have printing-preventive patterns in them, like e.g. the EURion constellation. This prevents the note from being scanned and copied and printed (since most printers and scanners are programmed to recognise them). The notes probably also have many other measures for preventing these things.
My question is: is there a LaTeX package that exploits e.g. this anti-money-printing functionality, so that it could be added it to a document?
I tried to look around a bit on CTAN, but couldn't find any.
Note: Of course finding something perfectly safe would be close to impossible.
