For an animated tattoo on your chest for instance, you'd shine a light hanging from a necklace that would strobe through various wavelengths of light tuned to illuminate corresponding inks, each different ink being used for a different frame of the animation.

This might be a horse running or a clown blowing confetti out of his butt depending on the sort of image you want to portray at your local rave.

I'd prefer to have a small drone follow me around 24/7, projecting what looks like an animated tattoo onto an exposed bit of skin. Obviously this would have to be pretty smart to get the orientation right and make the animation stay in the same place.

Ew, that gives me an idea that I don't like.

Know how people do body modifications where they stick stuff under their skin? I'm sure there's somebody out there that would like the idea of having a motorized bunch of bumps or shapes that would move if you hit an on button someplace. You'd charge it with an induction charger.

Very gross idea, but I'm sure there's people out there that would do it.

Re link: 2fries, that's pretty cool actually.

a1, wonder if that's where I got the idea. Didn't read the book but I was familiar with it.

I'm gonna say... plausible.

Someone's had too much confetti as of late, or something else much more sinister and mystical, one can only hope.

The world needs more confetti. No matter where it comes from.

All the links are so cool I am bunning everything here!
