I'm surprised the younger generation isn't embracing the new technologies available for tattoos.
Like being invisible/different in UV light.
Magnetized ink.
Del-Sol inks - changes colors when exposed to sunlight or UV light.
Lastly, why not? Embedded Blutooth...
Most artists I talk to won't even consider any of the first three options... they just make for sh*tty tattoos. The inks really aren't that good and need touching up a lot more often than more traditional inks.
I'm assuming your last option was purely a joke.
