Somewhat off topic: I imagine someone here could design a printer that a person could stand in or lay down in and use Henna to make temporary but very artistic and detailed tattoos on ones self to test these theories. This could be a way for people to test out ideas without making a permanent and painful mistake. Henna tattoos will last about 2 weeks or so before starting to fade. Alternatively there are people you can pay to have them drawn on you by hand.
