    Years ago I wrote a short sci fi story where a guy invents and open sources a system like crispr (before crispr existed) and takes it to burning man and gives everybody gene therapy to make glowing cephalopod tattoos that can appear/disappear/change color/all the other things that cuttlefish can do.

    The technology ends up being repurposed for all sorts of medicines/recreational purposes.

    Only after it's released, it turns out it causes some fatal disease a year later, which is only noticed because Burning Man was empty next year.

    So just fill your skin with this ink and use a laser to print any pattern.

    Looking forward to see human ads

    Wonder if it would be possible, someday, to make Cellular Automata out of these? Then could have skin level dynamic images.

    Instead of focusing on tattoos, could we work on this being used for bistable displays, like e-ink but using light pulses to transition each pixel?

    This is awesome and I hope it catches on, but the idea of "may be useful to people who want to conceal tattoos in some situations" seems far fetched, some make-up layer would probably be a simpler solution, wouldn't it?

      Hot springs and baths in parts of Japan deny entry to anyone with tattoos

        Usually a bandage will suffice to cover it. Even for very tattooed people, can be quite liberal with it.

          > Even for very tattooed people, can be quite liberal with it.

          Is this true for all heavily tattooed people, or are they more understanding if you're not Japanese?

          • computerfriend 6 hours ago
            In my anecdote, the tattooed person was Asian but non-Japanese. We did this several times, but of course it's still a small sample size, so take this with a pinch of salt.

        No. I'm black, tatooed and found an onsen in Tokyo that accepted me without any issues whatsoever.
      • duggan 7 hours ago
        Yeah, I guess now’s time to do the groundwork for building a tattoo empire in Japan.

    > These dyes are encapsulated in nanoparticles of polymethyl methacrylate (PMMA) — a medical-grade, glass-like plastic that is already used in medical implants and dermal fillers

    Nano plastics? :p

    Still pretty neat. I like the example picture in the article too

  • qwertytyyuu 12 hours ago
    That is so cool. I wonder if this allows for printing images with some kind of 3d printer like thing with a weak uv laser

      Got me in mind of the people nowadays "renting space" across their body - this would be an ultimate form ...
  • Retr0id 11 hours ago
    A cool concept, but regular daylight making it disappear again sounds pretty annoying.
  • phyzome 10 hours ago
    Despite the limitations, that is dope as heck.

    Regardless of the actual tech here, "he turned his tattoos off" has "the door dilated" vibes. Very cool.

    I'll have to read up on this. I wonder about it as a kind of e-ink?

    I'm sure there are a bunch of differences, but fun to think about perhaps.

  • RickJWagner 1 hour ago
    I’m older, with no tattoos. My oldest son has several.

    I’ve noticed with some amusement that several celebrities ( and non-celebrities ) have publicly announced and explained their recent tattoo removals.

    It reminds me of Dr. Seuss’s Sneetches.

    • causesothere 15 minutes ago
      I think your smugness is unwarranted. Some people get tattoos on a lark, and grow out of their meanings and eventually remove them. Some people think long and hard about their tattoos and they become personally commissioned works of art.

      I have two gorgeous sleeves with deep meaning, that I put hours and hours of pain in to. But they are for me. I love the art, I love carrying that art. I don't care about how they scan to others.

      It has nothing to do with being cool or fitting in.

      • xgulfie 7 minutes ago
        They weren't talking about you then
        • causesothere 3 minutes ago
          They likened tattoos to sneetches -- people who adorn themselves to fit in. Most tattoo havers are similar to me, and this person seems to be making a broad generalization about most tattoo havers.

    This probably has some cool applications for magicians to do unique tricks where certain things appear on their skin.

    is someone bored and going around hn front page editing all the titles. This is the second post i see in the last hour or so that was changed to a worse title.

    Why not have e-ink in your skin..
    • filcuk 9 hours ago
      Because skin is not just loosely hanging on but is attached to the tissue below.

    Does it turn the lymphedema off too?
  • self_awareness 8 hours ago
    Lol. Allow to violently perforate your skin with a set of sharp needles to permanently inject a pigment that can be hidden.

    Just wear a baby skin sticker!

    • ragazzina 7 hours ago
      Most piercings fit your description.
      • self_awareness 7 hours ago
        Piercing is one big perforation.

        Tatoo is a process of continuous small perforations sometimes for many hours.

    An alternative to "customizable/dynamic fashion" like this would be tags/markers on people's clothes that are invisible to the naked eye but can be detected by AR glasses, making you appear to have different clothing, accessories, tattoos etc to people wearing those glasses.

    But man none of the major company execs have a hint about any of the cool applications of AR sigh

    • chrisweekly 2 hours ago
      AR glasses are a scourge
      • Razengan 1 hour ago
        Because their implementation has been led by braindead suits.

        Watch the anime Dennou Coil and see what they could be :)

        • causesothere 13 minutes ago
          They will always be pervert glasses. They might also be cool non pervert glasses, but you cannot make them safe in a way that prevents them from being pervert glasses.

    Hear me out, implanted lie detectors with displays tattooed into the foreheads of politicians.
    • amateurCoder5 11 hours ago
      Simpler to just use a normal tattoo that says "LIE".

    Your auto-immune system does not like ink.
    • yahthatsart 11 hours ago
      You don't have an "auto-immune system". Auto-immune means your immune system is attacking your own healthy cells.

      Tattoos are fine. There's some evidence that maybe, maybe, immune system responses can be impacted by tattoos. But changes in immune system response does not necessarily mean impaired or negative.

      • pazimzadeh 9 hours ago
        kinda, but the system is not perfect.

        https://en.wikipedia.org/wiki/Autoimmune_regulator

        oversimplifying but in every person there are tradeoffs about attacking things inside yourself (viruses, cancer, etc) and outside things (parasites, bacteria, etc) and your genetics influences this. See the old Th1/Th2 balance

        anyway it was probably a typo on his part, he's such a sleepy guy..

        how about allergies?...ive seen recent tatooees and that shit aint good man
        • causesothere 7 minutes ago
          Some people have allergies to some inks. You definitely want to check with your artist and check what inks they use before getting a piece. There's still an outside shot that you'll end up with an allergy, which can be made worse with sun exposure.

          It's a risk. A very small one. You gotta figure out your tolerance for risk.
