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.

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

      Yeah, I guess now’s time to do the groundwork for building a tattoo empire in Japan.

    • computerfriend 14 hours ago

      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 14 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.

      • Karrot_Kream 4 hours ago

        I find that in the big cities (Tokyo, Osaka, etc) this isn't an issue anymore but it still is an issue in more rural parts of Japan. We were visiting friends in Akita prefecture recently and found fairly nice baths that did not accept tattooed folks.

    • pelagicAustral 6 hours ago

      Like literally any tattoo? or do you have to be fully blasted to get banned?

      • riffraff 6 hours ago

        depends on the bath, but they're generally understanding of foreigners with tattoos.

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

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

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 7 hours 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 hours ago

      They weren't talking about you then

      • causesothere 7 hours 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.

Lol. Allow to violently perforate your skin with a set of sharp needles to permanently inject a pigment that can be hidden.

      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

        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.

Your auto-immune system does not like ink.

  • yahthatsart 19 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 16 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 hours 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.
