The same book came to mind, but in the context of bodypainting. How long before we can make an inkjet body painter--I'm thinking of some print arms that rotate around the body on actuators that keep them very close to the skin. Careful motion tracking of the body to ensure it's spraying the right bit of skin as it moves. (I have a hard time imagining a printer that's fast enough to hold a position for, not to mention the need to breathe.)

And where exactly does that fall in terms of indecent exposure? Make sure the bits that the law requires covered have solid patterns at that point, it seems it would be legal.

(On the other hand, I have doubts about the practicality of wearing body paint in ordinary life--what can be durable enough to take what life routinely dishes out, but easy to remove? He also missed the fact that people only in bodypaint should follow nudist convention and sit on a towel.)
